Tagg is an iPhone app that lets you bookmark the real world along with your friends.

Tagg works with the services you already use, including Twitter, Flickr, Picasa, Jaiku, FriendFeed, Facebook, Mobile Me, and many other social networking, microblogging, and photo sharing services.

We are looking for beta testers that can make a commitment to providing ongoing feedback and being active in our young community. Please email us for an invite if you would like to join.
