The conpany I work for - just pushed out all the work we've been working on for the past few months. Basically joost changed from being a client based video player to being a webbased video player. Many people back when we did the initial release complained that joost was not available for Linux nor for PowerPC Based mac, we are now using flash. This means that the content on Joost is now watcheable from Linux, and older mac powered by PowerPC - and yes I'm aware that flash on linux sucks.
One of the other complains we had in the past was that finding the content was near to impossible. This is already better - as we changed completely the way search was implemented. It will improve over time too as we have added tagging. Tags are searcheable, so for instance here is the content taggeg with dolphin.
Just in case you might be interested we have some nice documentaries, music videos, and car stuff.
Ho and for those french speakers, there ia a french group, you are welcome to join !!
