What attracts you to social networking sites and what features are still missing?

[The answer is 42.]

If I were college age, I certainly would have both myspace and facebook; but now, I am way too busy for that. I will be putting up advertising sites for my videos and other stuff, but that's just to get 'presence' and not really go into it on a daily basis.

Technologically missing? It's too easy for abusers, flamers, and other obnoxious unfriendly people to get on the sites (including Yahoo! Answers). You can delete and block but they just come back under another name...

Too bad there isn't an Internet etiquette course you need to pass (and I don't mean just agreeing to the "Terms and Conditions"). Once you pass the course, you get an assigned ID which can only be associated with one e-mail. That should bring civility back...

Mind you, I am not against well thought out arguments. I am against people who resort to name calling and or other put-downs as opposed to giving a succinct argument with data backing up any claims and counter-claims.
