Have You Checked Out “Pownce” Yet?
I just got an invite today for Pownce, which off the top seems like a Twitter clone, but with a much more attractive design. I haven’t played around with it too much today, but I’m going to check it out some more later this week. If you are in feel free to add me as a friend, and I have an extra invite, so if you would like one just leave me a message in the comments area.
