Today, at the New Video Summit hosted at the VON show in San Jose, Bram Cohen, CEO and co-founder of BitTorrent was very much critical on Joost's business model. This upcoming start-up that wants to bring TV to the Web was founded by Niklas Zennstrom and Janus Friis who also started Skype and Kazaa. So Bram is not really going against beginners in the field but anyway, here's what he had to say about Joost:

Joost is kind of a "corky" thing, in that it is still very fundamentally based on the channel concept. Like I said this is kind of old video way of doing things. It's something that users are not especially attached to, unless you are really interested in Paris Hilton and Puff Daddy channel which apparently are very big because they are on the top level of Joost

But,

If you look to a site like YouTube that has a lot more content, it is not really organised around channels: there's some kind of loose organisation (keywords, recommendations...) and lots of means of discovery and not everything is based on channels.

Moreover,

Joost delivers things a cut above YouTube but not really high quality and that's not really where the future is. The future is in trying to get stuff to be high-def and today high-def is so big that for most people even downloading it takes awhile. Although i think there's still quite a market for that. What one should be focused on is stuffs that look good. You don't want these postage stamps things, you don't want YouTube level of video quality, you want something that looks like you're watching your cable, nice and ultrasharp.
