Joost is a “new” internet project that has been receiving a lot of hype lately, if I’m not mistaken they started an invitation system similar to GMail which makes the hype even bigger.
For the people that have been living under a rock for the last weeks/months, here is a small description of Joost:
A project that we think will completely revolutionize the way you watch TV. Joost brings you full-screen, high-quality TV on your PC or Mac – combined with the best interactive and community features of the Internet.
Basically it means TV on a computer but with cool features.
