If you follow someone that is online.

I don't, I see no point in 'following' people on here. it doesn't seem to do anything.

I follow people whose posts I find interesting, regardless of whether or not they follow me back.

if they write intriguing posts there's no time limit. Just depends I suppose on my mood

I don't ever unfollow people if I find their posts interesting, just because they don't wanna be my best mate.

hm I am not sure I follow you... ;)

I don't know. it all depends on you I guess.

One hour and sixty minutes.

I don't normally add and wait.

I don't worry about it....

I will wait forever

I have no time limit, don't really care

oh I just stalk them for my personal amusement
