I was suprised not to see anything about Whrrl (whrrl.com) yet. It's a pretty sweet twist on social networking. Check it out...

You rate your favorite restaurants, events, etc. and other users can then get recommendations of those same places by their friends. You can even "check in" when you're there and your friends are notified if they're arriving at a place where you're at. Pretty sweet...
