Jyte is a place to make claims about yourself, others, or just about anything. It’s a place for web surfers to see what you are up to and what you’re thinking. It’s a place to learn more about friends, and for others to learn about you through your claims, votes, and cred. It’s a place to build out your social network and share it with other sites. It’s a place to use your shiny new OpenID, and a place for people who see your OpenID around the web to discover your world. (Quote from the Jyte Blog)
You should check it out, but as a warning … it is highly addictive.
