I just downloaded Joost from www.joost.com and it looks beautiful.
There was a lot of breaking up in the video but that is probably because it is too new. I understand that it is based on p2p technology, so the more people the better. There is also a pretty good selection of content and the best part the ads are less 5 seconds – completely un-noticeable.
There is also a bunch of social features, which I will review later. I haven’t had a chance to play with them yet.
