meh Im pretty selective.. its nothing personal for most.. but if I think theyre a minor or even too much trouble I wont.
Very rarely. I never request others almost to add me. But if others request me having studied their profile if I like and if I am convinced I shall add them.
Most of the times :)
I like my circle to remain on the smaller side. If they don't bother to message me first; I don't bother adding them.
