Twitter, Facebook and Myspace

Well, someone suggested (quite a few someones) that I needed to sign up on all these new networking, socializing sites...so I did. But I need a lesson on what to do and how to do it so I don't (1) look like a complete idiot (don't need any help in that department) and (2) bore you to the point where you run away with hands flying in the air and screaming ever so loudly. Or at least to the point of tears. So bear with me as I bring myself up to the technological times and think of how crazy my grandparents and dad would think this is.
