Twitter: where people post zingers, brag occasionally and link to their blogs.
Facebook: where people take quizzes and nobody posts anything (anymore).
Myspace: where the media finds photos of you during your humiliating trial.
FriendFeed: where you’re pretty sure you have an account.
Tumblr: where people post photos of themselves and/or their food.
LinkedIn: where you are apparently the co-founder of several companies.
