AllergyNotes New approach taking hold: Facebook is for close friends and Twitter is for business - any thoughts? 
beryltheperil if twitter would only be for business, it would be boring. beryltheperil what I like about twitter is the randomness & playfulness mixed with the serious, it's nicer-less cumbersome.
medconnect agree - twitter too instantaneous to be used only for friends - friends never online same times as me, but colleagues always are 
omearamd I think @NathanBowers said it best, "Facebook is for people you used to know and Twitter is for people you want to know."
