Yep, I only recently got a Facebook account after a few years of "Oh my God! You don't have Facebook...how do you live?!?" and it's so boring, no-one speaks to anyone they wouldn't do usually!
Also, I seem to have accumulated a fair few friends who post status updates that invite questions like "Sooo annoyed at him right now!" prompting all their friends to say "Aww, wats up hun?" and proceed in code based conversation so that the conversation posted on a pretty public place can remain private!
