edit: also I haven't logged in and checked yet, but it'd be neat if you have a trending videos, hot videos, over a few time periods, etc. Maybe by category also if you get the youtube metadata, so [view hot videos in the "news" category in the last day]. Definitely tie into the youtube gdata API if you haven't already.
I also agree, you should just stick the public stream (or an abbreviated version of it) on the front page, there should be no steps required to get a taste of how things works. At the very least, a screenshot of how it looks on the front page...need something to entice me to log in.
Once I logged in though, yes I dig it. I like that you can retweet from within the interface. The UI is simple and works quite well, push that out to the front page!
It's nice but the public stream is pretty much like http://www.youtube.com/videos?s=pop - right? I'm not sure how this is better? and my private stream was kinda empty so perhaps its just me not being your target audience, or my friends not being into video enough!
