If you are interested in new social networking sites and changes to existing sites such as MySpace, YouTube, etc., you should check out Mashable.com. It's probably the best blog about social networking and what's happening in Web 2.0. Great resource.
Today, in their MashTracker section, they featured Zaadz, a social network of people who want to change the world, which just received a major investment from John Mackey, CEO of Whole Foods.
If you are into social change, check out Zaadz as well. It could be a great resource if you publish new thought, self-help, or spiritual books. Note: It's a slow site to load. You will need a fast Internet connection.
