Stream-style following page
What is the use of following other people? Currently, it only enables having a followers/following list on your profile. Wouldn't it make more sense to show the latest posts of those users?
That way, we could bring a lot more optional social functionality into NodeBB - I think about a "stream" page, similar to Facebook, where things your friends do, important topics etc are aggregated.
But maybe this is too much already, so please keep the two ideas separated when thinking about it
