It's a pretty bold move to launch an open source service like this, especially one that is as complex as a video sharing site. One would think a gradual increase of user base would be easier to handle than a sudden influx of people at a moment when one has been scrambling to meet a deadline.

Good thing they/he is not afraid of postponing the release and making sure it's ready. And if it works well it will be one hell of a release. Fingers crossed. :)
