Simple - you can upload videos to Youtube and have them go live straight away. With Google Video, you have to wait for your video to be viewed and checked for suitability first. Not to mention that Google's upload system is a lot more involved than Youtube's.

You might remember me rating Grouper before now. Well, Grouper's user interface is still my favourite - fresh, clean, fun. But Grouper falls short on what's perhaps the most important part of a video sharing site: quality. The resolution of videos on Grouper is considerably - unacceptably - lower than that of Youtube.
