danger! warm social bits!

I've decided to take a risk and release some code fresh from the oven, it didn't even cool down yet. I hope this will help get some feedback.
as I've promised, I've got some changes planned, and a part of this is making the site more social - so I've added general messaging between users, and quick browsing your contacts / finding friends that aren't in your contacts yet.

as usual, the best way for you to get an impression is by going to the site and trying it out.
I hope this will help me understand the users' needs and plan the next steps...
enjoy!
