If you read this blog, then you know that I'm a big YouTube fan. Google is now competing with a site that has much better performance.
My favorite video site is soon to be VideoJug once they get more content up. I realize that the name implies an entirely different type of site, but these folks are putting together a library of thousands of how-to videos. Some are produced in-house and others will be uploaded by members.
All content is approved before it is posted, so VideoJug should turn into a very high-quality site.
