Soapbox (MS's YouTube Competitor) is nice!
I got into the beta today and I really like where it going. While I can't show you what it looks like, I can say that there is a lot to like about SoapBox (Microsoft Live's Answer to YouTube). The experience of viewing, commenting, and tagging of video is a better experience and looks really nice. If you want to go the link, you can sign up for the beta. I like a lot of how they are handling video that is better than Google and YouTube.
UPDATE: Fixed bad URL to SoapBox.
