Amen i feel the same way, to much junk for me but my wife loves FB.I can't find a use for either. I used to have a facebook account....hmm might still have one, not sure. Do those things have a use by date like milk?
Twitter, well I could never find a use for it, so I know definitely that I killed that one.
What? Google who? Last I heard they published your details to spammers or something equally antisocial.
