What do you want to know about Joost?

Plenty of blogs have recently been buzzing about Joost, the new online video site devised by the creators of Skype and Kazaa, which was formerly known as the "Venice Project." I've been beta testing it too, but rather than posting a basic walkthrough, I'd like to know specifically what kinds of questions you have about it. So, post your Joost inquiries in the comments of this thread, and I'll answer each one in an upcoming thread about my experience with the beta.

You can be as general as you want ("Is it really going to kill YouTube?") or as specific as you want. Bring 'em on!
