I just got an invite token for Joost now that they support OS X, (thanks for the invite xeni). So far it seems pretty cool, I watched a couple of national geographic episodes. The way in which Joost stops for commercial breaks is annoying, although it is only shows 1 short commercial, the timing of the breaks doesn't coincide with a stopping point in the actual media you're watching. The interface is really slick, and the social networking aspects seem pretty damn cool, although I didn't find anyone else watching what I was watching so some of the features weren't really useable, like chat for instance. There is also very little content in the system right now, but I'm guessing that will change rapidly. I searched for "monkey" and found nothing, while photography turned up only 2 hits. If Joost takes off I can see the big networks putting their content on it, and that would rock.
