yipes!

I'm turning into a social-networking fool!
Have added friends from grade school, high school, college, past jobs, and someone who used to mod a fan-newsletter I subscribed to oh... almost FIFTEEN years ago to my various MySpace, Facebook, LinkedIn and Twitter accounts in the last few weeks... how do people keep up with this?!
It's amazingly cool to catch up with everyone, and makes me realize I'm not as much of an island as I thought I was...
