Yahoo's Mash

I came across some details on Yahoo's new social networking site Mash. Seems they are trying to compete with MySpace, Facebook and the like. It looks like a nice mashup with modules for blogs, games, photos, etc. An API is also in the works so developers can add their own modules and content. We'll see if this is going to pan out or if it's just another failed attempt by Yahoo. Seems like this is also an area where Google is still not dominate either.
