I remember how quickly people stopped using IM and moved their entire online presence to Facebook, including the announcement and discussion of planned events.
As an IM user who never moved, it kinda sucked. :)
I guess you could say the same about the move from ICQ to Windows/MSN Messenger, though.
I have friends who post annoying stuff (blocked from feed) and friends who posted really inappropriate comments on my stuff (unfriended.)
Is there some part to teen usage that discourages blocking a friend's feed or unfriending someone?
Possibly, but for me I guess that seemed like losing a valuable news source unless it got really bad, which had happened.. Looking back though, deleting was probably too extreme, and I still use Twitter /and/ Instagram.
