Almost every section in the profile summary page can be sorted.
- We can sort the questions and answers by age, activity, or votes
- We can sort badges by class, name, or age
- We can sort bounties by active, earned, and awarded
But there is no sort option for the accounts. It is always sorted by reputation.
With so many sites now, it seems like SE only wants me to pay attention to the 5 sites I have the most reputation, rather than giving me the option to sort by activity, reputation, and maybe another criterion (age?).
I have 15 accounts currently, and while I am only really active (from an asking/answering standpoint on MSO and SO), I'm trying to explore some of the other sites and have asked a recent question on Seasoned Advice. It would be nice if I could sort this list by recent activity so I can see rep changes or other changes in activity at a quick glance without having to click "view more" and then find the site I want to see.
Obviously when it is just 1 new site I asked a new question on, it is easy enough to keep tabs on the posts, but if I decide to ask or answer questions on 2 or 3 new sites, it would be nice to be able to see which of my sites has the most recent activity from my profile.
The definition of "activity" is going to be subject to some debate and probably in be based on what is easiest to capture quickly via caching but in my opinion the best actions that would bump an account would be based on stuff that happens without your own actions:
- Having a question answered
- Any rep change
- Having a post edited
- A comment on any part of your post (not just stuff that would get you pinged on)
- Updates to a Favorited post
- Earning a badge
- Getting pinged via comment
- Follow up comments on posts you commented on (this one could get annoying but would be helpful in cases where someone forgot to use an @-comment)
Obviously if it is based on actions that you perform yourself, it is somewhat pointless as you know what sites you were performing actions on, but including "Asking a Question" or "Answering a Question" in this list would make sense since those are the primary actions of the site.
I would not include actions like performing reviews, making edits, voting on posts in the actions.
For sites outside of SO/MSO, Meta activity using similar criteria should also bump an account.
