I would expect that:
- Sorting by newest will show my most recent answers on top (this works ok)
- Sorting by activity will display my answers with the most recent votes on top (this does not work. The results displayed are exactly the same as sorting by newest. On my current case, this answer https://stackoverflow.com/a/7391328/345490 should be listed on top when sorting by activity since this is the one with most recent activity; instead, I see the same results as sorting by newest)
- Sorting by votes will display answers with the highest votes first (this works ok)
In conclusion, sorting by newest should display the ones in which I have participated more recently on top. Sorting by activity should display the answers in which others have upvoted/downvoted my answers more recently on top.
