The new video sharing features of the formerly photo-only site Flickr are different: the designers obviously thought a lot about how to implement video without just cloning how YouTube and everyone else does it.
The key thing is that videos uploaded to Flickr must be less than a minute and a half long, and no bigger than 150 MB. That's a limitation, but also a gift. It forces you to think about what to upload, and if you have a longer video, to edit it down to its essence.
My first video upload there is a good example. I had to take a video of my band that was already only a few minutes long and make it even shorter. I had to cut out non-licensed music and any other extraneous bits. In the end it's only one minute, but it still gets the point of our act across, even without any singing at all.
I think the time limit will generate some creativity in the Flickr community, as well as avoiding those interminable videos that take forever to get to the point. Even if a video is bad, you'll only have to waste 90 seconds on it. We'll see what happens within the well-imagined constraints.
