I've managed to get myself a Joost invite. This is the future of TV. I've been interested in the convergence of TV and PC technology for some time, and Joost looks like the best combination I've seen to date. It took me about 2 minutes to get this up and running, and my initial experience is positive. The picture quality isn't great, and I've been disconnected once or twice from the shows that I was watching, but it's still a hell of a lot of fun.
I don't have any invites yet, but as soon as I do I'll pass them around. It looks like Joost may be days away from launching, so that mightn't even matter soon.
Update: I can send invites now, so if you want one, just drop a comment with your e-mail address
