It is still in beta but got an invite within a few hours, I've just set up my profile and so far so good, although I don't see the point yet as it is similar to Friendfeed without some of the features I like, such as rooms and the real time view. It has a list on the side where you can choose whether to look at photos, videos, blogs etc which is quite nice as some of the features (last.fm for instance lists everything you listen to, the small album cover is cute but it can create a lot of noise). It does not have that many services you can add yet but I keep it going for the time being, we will see.
