It looks like YouTube has finally started supporting HD content. I have been using Vimeo HD for a while now, but in order to get unlimited HD uploads I would have to pay $60. If YouTube offers a better deal than that for free, I might just have to switch over to youtube (which is too bad because I thinkVimeo is a great site). For now, there is no ‘HD’ button I can see on the actual YouTube pages, so to watch a clip in HD you have to append ‘&fmt=22′ at the end of the URL (Edit: They have added a “Watch in HD” button now). Here is an example of 720p HD vs SD from youtube (click play on both at the same time to see the difference):
