Normally, when a user edits one of my posts, I receive a notification like on the following depending on the case

  1. User has editing privilege (click to visit revision)


  2. Users' edit is submitted to review queue (click to visit review queue)


The above notifications were received instantaneously (or less than 30 minutes, in case caching is supposed to be the answer) as the edit was done/suggested.

But I did not receive any such notification today (yet) on an edit made on my post here. I think it is a possible bug and should be looked at. The recent notifications list I have is shown below:

not. list

  • What does stackoverflow.com/users/1190388/… show? Oct 21, 2013 at 0:43
  • @MartijnPieters Yeah. The revision history does show the edit being made.

  • Does a browser cache clear help here? Most likely the global inbox isn't being reloaded. Oct 21, 2013 at 0:50
  • @MartijnPieters Nope. I didn't receive a notification on \@animuson editing the meta post either.

  • Minor edits don't get notifications. I think animuson's edit on this post is considered minor.

  • Note that the top one says "Code in your answer..." - it might not have detected any code changes in animuson's edit, therefore not notifying you of the edit. Oct 21, 2013 at 1:20

In order to reduce noise sent to users, we only notify when "substantive" changes are happening on their posts.

There are a few rules in how "substantive" is defined, but typically one of the following should be enough to trigger a message:

  • the edit to a question title should be over a threshold (10 characters on most sites)
  • the edit in the post body should be over a threshold (10 characters on most sites)
  • the edit in code sections should be over another threshold (2 characters on most sites, no threshold on sites with syntax highlighting disabled)

The thresholds vary from site to site. Retagging only is not considered "substantive" hence will not send notification. The threshold calculation is based on the plain text of the rendered post, not the Markdown, so things like formatting changes and link changes won't count toward it.

    What about tags only or title only edit? Oct 21, 2013 at 13:08

    Is it possible to enable all notifications manually through some settings?

    Do such edits still push the edited post on to the front page?

    Do edits only to the title cause a notification? (Always? Only over some threshold?) Titles are pretty important and even a few characters can be significant, so I'm wondering what the rules are for those. (I've definitely had the meaning of a title be changed without the edit triggering a notification, but it was long-enough ago that I don't remember the specifics.) Jun 14, 2015 at 3:33

    Sklivvz: I'm unclear on how to cast a vote on this: yes, your answer clearly explains what's happening, but no, I don't like it (at all). How to proceed? Ask a new question for a feature request to make this a user setting?

    Scaling up websockets is a big issue. At the moment we have around 400,000 open websockets, typically, so what seems like a small change is effectively a pretty big amount of more load that we would be pumping there. There are other better things we can do with any extra capacity we can spare...

    Really would like to receive these notifications. Now I feel like I need to recheck all my posts for bad < threshold edits.

  • @JasonC, it seems like that should be a pretty simple Data Explorer query to set up. I don't have time at the moment, but something about owneruserid = (me) and owneruserid != lasteditoruserid, and you could even throw in a join to the users table and check for low reputation editors. (If you write one, please post it as an answer here and, if you wouldn't mind, ping me!) :)

    @Fabby There is a feature-request regarding that.
