"My overall impression is that despite what other news agencies have said (probably without having access to the real TVP client) Joost is NOT a YouTube killer. Most likely they will continue to co-exist for a long time, simply because Joost is a P2P TV application while YouTube is a user generated video site, where everyone posts (almost) whatever they want (which you cannot do on TV). Joost doesn't bring a better alternative to the Internet video, it brings TV to the Internet, thus becoming complementary to YouTube, rather than its rival."
