A “Friends List” on StackOverflow would be nice
I want to Favorite Users. There are several users whose questions I always enjoy reading. I would like to be able to Favorite them so I don't have to remember their usernames.
If you want to follow a user, you can bookmark their activity feed, go to their profile (by clicking on their name), and go to the activity tab, for example mine is:
If their user name changes, we'll redirect you!
But...we have no plans to make the site any more "social" than this with respect to following users, that isn't our focus.
