We have amongst others:

Personally I have used the last seen field a lot. It has never been to check how often etc. people are on the site(s), albeit I am sure some do – and as we know, big-tech etc. are among these. SE included – which makes the removal kind of leveling the information to the elite only. (Do mods etc. see this field? Another question, I guess.). One thing for sure: this information is tracked nonetheless. Hiding it from you does not make it disappear. If one uses Gmail or the like for it then, duh.

But in relation to the myriads of other uses like “has my comment likely been read”, “how to help this new user”, “is there any point in answering this narrow-scoped question” etc., as for the latter answering old questions where the questioner has not had any activity the last N months, or even days, is skipped faster than a heartbeat now.

Quite often as well, it is in relation to clarify questions; something that feels like pulling teeth at times. You ask for some information – wait and check if the user has seen the comment, wait some more. After N days you post an answer nonetheless in hope the questioner someday comes back, or you ditch it altogether if they very likely have seen the comment, but they did not respond with anything.

I do understand that people do not like it. Heck, I even think it is good that people do not like it. But, and there is a big but, the use of it is very helpful in a Q&A site. That's simply part of the nature of the beast.

So what should we do about this?

I strongly believe that the SO community can come up with a better solution than removing it altogether. I throw out a few of the top of my head suggestions and likely someone can come up with better suggestions.

  • Last seen N days ago
    • Limit the information to N days. Say a user has not visited for 30 days; then say not seen for 30 days, 31 days...
  • Opt out
    • Let the user opt out of showing last seen, optionally implementation-wise with a shown nonetheless if above N days.
  • Opt in
    • Just as with cookies. If not set by the user, show a dialogue asking if this information should be visible.
  • Dialogue after N hours
    • If not visited for N hours, show a dialogue with options such as “status online”, “status hidden”, ... and the option to set this status on the profile page. Keep the status without dialogue if manually set.
  • Opt out at N reputation
    • Make the field an opt-out after reaching, e.g., 50 reputation.

Conspiracy theory

I have to throw in a conspiracy theory to spice things up. OK, heh, not as much as a conspiracy as an example of the negative effect it can have.

I have seen an influx of new users asking questions. Perhaps I have been away for too long, or not noticed it in the same way before, but there are a lot. The issue with quite a few of these is that there are many that ask a question and never visit the site again. (Noticed before removal of the last visited field.)

When active users see this, some take questions with a pinch of salt. This of course likely has an effect on the Q/A ratio. By this one theory is that this field was not removed due to privacy, but in an attempt to raise the answer to question index.

However: I believe this can have the opposite effect. Quite often as well, new users ask questions, check in later, and then check in even later to see an answer. Without the last seen, potential answers go unwritten because one assumes it is likely the user has not visited for N days.

It has as much to do with respect for the time of the ones answering questions as to the time for the ones asking questions!

OK. Enough of that. Q&A sites are dating sites. Questions (and answers) are linked to the person that pushed them into the wild. Just like hunting bears, (not that I would hurt those furry puppets), is knowing how long ago the bear crossed that hillside.

Without this it's more like a mailing list with a somewhat nice UI.

Thank you all! (post scriptum)

Thank you all for thoughts, views, speculations, ideas et cetera en masse!

I post this as an “answer” as I do not want to add more clutter in “the post”.Revised after feedback. The point is that I do acknowledge and value the discussion.

  1. Thought was to give this a somewhat light tone. Sorry if it it did not come across as intended :).
  2. Was not meant as a “these are the arguments” – I have some, but also admit a lot of the use has been on auto pilot where arguments can be hard to describe.

There is a lot of good points brought forth from all corners. My thought and belief has always been, in this kind of matters, that one should encourage an open debate and willingness to actually listen to, criticize - both harsh and soft, be passionate about, fight for, try to convince, argue good, argue bad, throw out thoughts and ideas dumb, good, brilliant – but not the least accept that we are tuned differently.

One thing is for sure: this is a topic with a lot of good points in all camps – and the intention is in no way to close or conclude anything – besides once more emphasizing this is a topic with a lot of good arguments.

The “site”, (it's a lot broader, but not sure what to call it), is a community, - a conglomerate of themes. We have mod's doing an incredible job and the fabric (y'all) contributing to the enrichment for generations for all from assembly coders to ... ____.Most things is assembly in a way?! Part of my reason for saying all thisSuddenly having a feeling of being a pink cloud philosopher; but let it go. is that I hope the entities surfing the upper layers of this ecosystem see discussion, and perhaps more pre change discussion, as a value that both enrich but not the least acknowledge the users (aka the fabric).

p.s.p.s: Have decided to “simply post” more often then is in my nature. So I jump off the wagon once again.

Unfortunately, we've not been given any official explanation for why the "Last seen" field was removed for everybody except the site's diamond moderators. I've always found it challenging to deal with an action that I don't offhand agree with when I don't know the reasons why it was done. If I knew this, I might even agree with the decision. Otherwise, if I'm going to try to convince the other person or group to make a change, it's difficult to give an appropriate rationale since there's a good chance I'm not actually addressing their main concerns. Instead, I can only just guess and try to deal with what I suspect the reasons are.

Regarding this change, animuson's comment states

We've actually had quite a few complaints in the past that a "Last seen" indicator public visible is a creepy and intrusive thing to have on a user profile. So I imagine the disappointment will be very 50/50 here. ;)

I surmise this is the main reason for the change. Although I believe this is a valid concern, this field is also useful for curating in multiple ways, such as described in the question here and in various answers of Some changes to the profile while we make it responsive. As such, I suggest implementing a compromise.

First, though, note that although the "Last seen" value was stated to within a minute or even seconds, it was actually only approximate. It was not always updated whenever the user took an action, e.g., posting a question/answer, commenting, editing a post, etc. Also, on quite a few occasions, I've noticed this value for a user is even well before the time of their post. I don't know of any official explanation for how this value is determined, including what granularity is used. However, since I don't recall seeing any "Last seen" value more than about 15 minutes before the last action I know a user has made (e.g., when they posted their question or answer), I assume this is roughly what the granularity is.

My suggestion is to increase this granularity period to about N hours, for some N = 1, 2, 3, etc., for use in time periods up to one day. For example, with N = 2, then for up to 2 hours, the "Last seen" value would show "2 hours ago", for between 2 and 4 hours, it'd show "4 hours ago", etc., up to 24 hours. After that, it'd show the same value as what the network profile account tab (if available) shows, e.g., "yesterday", "7 days ago", "1 month ago", etc. I believe this removal of apparent accuracy (i.e., up to within seconds or minutes) and the increase in granularity reduces the privacy concern, but it's still accurate enough to help ensure curators can mostly continue using the "Last seen" value as they were before.

Update: I didn't recall it at the time I originally wrote this answer, but PM 2Ring's earlier comment to animuson said

But if you insist that the old "Last seen" data is too much of an invasion of privacy, then you could just round the last seen time to a larger quantum, eg the nearest 6 hours or nearest day.

This suggestion is quite similar to what I propose here. I was just reminded of this by PM 2Ring's comment.

    @OlegValter But “last seen” is not actually gone. It’s still visible (albeit with less granularity) in people’s network profile and it is apparently still available through the API. My guess is that they’re not going to talk about it until they’ve decided what they’re actually going to do going forward. The removal of it from the profile was obviously not thought through very well and now that they realize that it’s more complicated than “some people think it’s creepy” it would be foolish to make the problem worse with more hasty actions or off-the-cuff comments.

    @ColleenV - I understand that (and we have a userscript that restores the metric in full by using an API), but that's likely wishful thinking on our part. A proper conduct would be to reverse it alongside the other change (they did restore the "member since", after all) and start thinking what to do next afterwards. As things currently look, though, is that there is animuson's comment of the form "people complained, we took action - who are you, again?", and that's it - does not look like they are considering anything to me. And if they do, there is a clear failure to communicate that to us. Commented Aug 24, 2021 at 20:37

    @OlegValter All the more reason for them to keep mum until they have an actual plan. You’re probably not going to respond favorably to anything less than reverting than change, but it’s apparent some of the community doesn’t want that change reverted. Anything they say before they have a clear path forward is just going to make things worse. The account age was not controversial like last seen. I am going to be patient because they’re trying to fix a mistake, and it’s better take the time to fix things once if you can instead of rushing and having to fix it 10 times, upsetting everyone.

Here's a "small site" take on this whole situation.

Over on Anime and Manga, we have contributions from contributors who have long since left the site or the network.

It's useful to see if they're still around or not to get a sense of how healthy (or unhealthy) the site is.

The workflow for seeing if someone would answer your question is a fairly moot point; I just want to know if the people who amassed some thousands of rep on the site are still around.

    Yes. This is another good point. I regret (rather much) I did not let my question mature more before I posted it (which I sometimes do).

    That's limited, off course if a user logged in yesterday or last year there's a significant difference in probability the user will accept and upvote an answer to their question. So I'm seriously more inclined to answer users who have some recent activity. And their logging in doesn't mean they'd comment or review or do anything that would show in the activity tab. So there is a definite interest in the "last seen" field.

  • @TylerH: Not necessarily. Not going to mince words; Anime and Manga is a tiny site with very sparse foot traffic. It's not unusual to see users go "dormant" for more than a month, only to pop back up when the next anime season comes through or when a new release of a manga comes. Since there's no predictable schedule for that, activity on the site varies wildly. So having higher resolution is desirable to see just how active the site is.

    Commented Nov 3, 2021 at 14:40
  • @Makoto OK, so if a user is dormant for more than a month, having more granularity than "this week" is not needed. If they are dormant for less than a week, that's still not "long since gone" or even a problem for shows which might only air one episode a week. It's not like we can have precise granularity for lengths of time beyond a week anyway (we never had that before), like "last seen 87 days ago"... IIRC it was always vague to the month once it got to the n months, up to 12 at which point it just became "last year" or "2 years ago" etc.

Checking if a user has been active to determine whether they read your comment is an anti-pattern. Just because I was online at a certain time doesn't mean I read my inbox messages, or that I'm in a position to reply just then. It also doesn't indicate if I actually can or want to respond.

What you actually want there is a notification that a user has explicitly read a comment, you're just using the "last seen" as a proxy for that. This kind of notification can be useful, but in general I find this type of feature annoying because it adds a bit of pressure to respond quickly. If there is no way to check if a user has read a comment, you can have the polite fiction that the other user probably just hasn't seen your comment yet even if in reality they're just not in the mood to reply right now.

In the end it's always a bit of a gamble when you interact with a new-ish user on whether they will abandon their question or not. But it also shouldn't matter as much for good and interesting questions, it mostly matters for questions that don't have enough detail to stand on their own. And we always answer for more people than just the original asker, even if they never come back other people will read the answer and hopefully find it useful. Of course if you answer questions that are extremely specific and not of interest to anyone else you have to live with the risk that the user simply won't come back.

You also don't know if a user has set up email alerts for inbox messages, which I think is even the default for new users. And in this case using the "last seen" as a proxy for whether they will see your comment is entirely wrong anyway.

I think it is a good thing to remove the ability to check whether a user was online very recently even for this use case as it emphasizes the SE idea that the questions and answers matter more than the users. And you can still use the post itself and any previous comments by the user to judge how likely they are to interact and respond.

I think a way to distinguish if a user is active at all anymore is a valid request. But I don't think we need any granularity here, a simply "user has been active in the last 30 days or not" flag should work for this purpose. I also might want to make this global and not per-site, as for the question whether they're likely to interact if you comment or post on an old question of theirs that is the relevant point, whether they would see the ping in their inbox, not if they have been on that specific site.

I'm againt any kind of preference for this, every additional preference has a cost and we don't want to just pile them on.

  • 4
    A lot of fair points. Though; it's only used as an approximation it's a bit hard to paint a clear picture due to all the varying factors in regards to a question. If a comment asks for very simple information like how big is the file?, which OS do you use?, what does the command XY say?, and what not. If user have visited the site after such a comment one can assume they likely have read it. If they do not update or respond N days after that either give a generic answer, - not to the detail one might want, - or simply forget it and move to other questions. Commented Aug 23, 2021 at 23:41

This has been partially restored with reduced granularity. See this FR marked status-completed with the developer comment underneath.

The current granularity seems to be between more or less than a week/month. Some examples:

  • Last seen this week
  • Last seen more than a week ago
  • Last seen more than a month ago
  • Last seen more than 1 years ago
  • Last seen more than 2 years ago

    It also goes into "a year ago" and "n years ago". I haven't seen a "n months ago"

There's a fairly flawed premise for one (but not all) of the arguments for bringing back the last seen field:

"I want the user who asked the question to be able to select my answer as the correct one, and freshness matters"

While the 'obvious' goal is to find the 'right' answer to a question for the user to ask it, we have a slightly forgotten goal of "building a knowledge base" or "helping the next guy with these issues".

To borrow a bear metaphor: while not getting your face eaten by a bear, or more traditionally a leopard, is laudable, if you see bear tracks, it might be worth posting a warning that there could be bears there.

Freshness matters a little less than folk assume, and one can quite happily post a new answer to a decade-old question to enrich the commons.


An interesting metric to show could be "time between views".

As the questions may well be the answers. A "wrong" answer may lead to discover wrong questions. That would be science. I think this is not a Q&A dating site. More like a mailing list, yes, but better. Let's not seek for immediate recognition as in a typical social network. Knowledge is atemporal.

It could be interesting or encouraging to know that what is written is not completely ignored or forgotten in the vast space of the Internet of internets of internets.

It's up to the reader to discover why the question doesn't have any answers. If it's easy to find the answer in another place, you will get there sooner than later. If it's a matter that few people know about, it will take longer to someone trespass the frontier from reader to writer. The time between views is be connected to the usefulness of Q and A.

I have just signed up to the community. The very thing I did before deciding to do it, was to calculate how many visitors had viewed a question that may go near where I need to be to finally answer it myself. The post was dated 1 year 4 months ago and had 168 views. That is one view every 2,985 days.

Many times one find unanswered questions, I personally don't get upset about it; I just keep searching. This time there were a number of replies to this question, and there I was, surprised to find this hidden fine Internet-jewel: A question and a pair of possible answers to what I think would be a fairly uncommon behaviour that I would like to implement on my Ubuntu based machine. Then somehow something moved me to feel the confidence to sign up and write a new point of view in this rare occurrence, because this "few" people represent ~0,00000002% of the people on earth.

All of this happened to me a long Internet-time ago (maybe two hours ago today). I didn't answer finally to that question (it was easy to get an answer in other place). Instead, I found this thread, and the first that I saw after my register, in which I have spent a considerably amount of time and effort to answer. Now it seems to me that the other post is a very healthy set of Q&A that has served its purpose. In terms of "# views" it's not forgotten, despite one year in human-ages it would seem abandoned.


You say there are new users who ask a question and then go away. It has always been like this and always will be.

This is not a problem.

You are not answering a question just for the questioner, you are answering for the community. Assuming the question is good, it will instruct other users in the future, irrespective of whether the OP actually sees any Late Answers or comments.

The Last Seen value of a poster shouldn't affect how you respond to their post.

    Maybe it shouldn't affect posting a full answer, but it can affect posting a comment, for example, asking to clarify. Only the OP can clarify, and knowing they were last seen 10 years ago would save you from wasting your time writing a comment. Commented Aug 23, 2021 at 10:36

    I have to disagree with “This is not a problem.”. It is a problem in various of cases, the most important being clarification of questions. And, if I'm being honest - simply courtesy. You ask someone to give of their time to answer you, sometimes using a lot of time. Asking a question and turning the back is simply extremely rude imo. Sure one can help people "down the road" or what ever, - but then it also becomes a question of - “do I really bother with this Q where user is a muzzleloader seemingly not even caring if an answer is posted or not”. Commented Sep 3, 2021 at 21:07

To restate what has been said elsewhere, the "All Actions>Sort by Latest" is the closest "replacement" for all general purposes. In my opinion, it makes more sense.

For high-rep users who may or may not be actively contributing: we don't care when the user last viewed a page on the site. They could be inactive and they may have simply reached there while going through Google search results. There is a fair chance that an effectively inactive user would find themselves in this position and choose not to open any pending notifications. We similarly don't care about when they last voted: they could have got there from Google results, voted on the post that helped them, and moved on without checking old responses.

For new users: you shouldn't have to worry about whether they're around to accept your answer or respond to your comment. If it's a question worth answering or comment worth posting, your content will have value to future viewers and should be posted irrespective of the OP's activity. An answer will help future askers and a comment will help someone else edit the post to improve it (or encourage future curators to close/delete, if the request for clarification is a huge deal).

We care about their last publicly visible action, whether it's a review, accept, or comment. That's the guarantee that they're interacting with the content of the site in a significant manner.

Overall, I don't see the strongest of reasons for removing the metric, but I don't think it is a huge loss and it is not worth so many meta posts.

    I agree with this answer. "Last seen" doesn't really tell you anything useful: it could just be that a long-open old tab out of 20 open tabs has refreshed itself. Latest action does tell you when the user actively engaged. And perhaps more importantly, it's intuitive that leaving a comment or making a post leaves a publicly-visible trace that you were here; and it's not intuitive that simply visiting a page (or letting an old tab reload) leaves a publicly-visible trace that might mislead someone into thinking you're deliberately ignoring them.

    I think the request in the question would be better served with a feature request for a feature purpose-designed for the particular use cases. For example, something equivalent to Whatsapp's two ticks for whether your comment was seen by the person/people it pinged. Then the discussion would be more focused than asking to continue to use a side-effect of something that makes some people uncomfortable for a use case it wasn't designed for.
