Pownce.com is a new social networking site. It’s different from the rest of the social media sites I’ve seen. It’s simple – you can share music, files, urls and dates with your friends. It’s also invite only right now, and I happen to have some invites burning a hole in my pocket. If you’re interested, just drop me a note, or take a look for yourself – http://www.pownce.com/nathanj/.
