I use Google and EyeSpot, numbers 6 and 10 on this list. They have the least intrusive advertising and seem the best for personal clips, that may not have mass appeal.
I got this from a friend's blog and I just had to post this. It's a very haunting video of the 9/11 attacks, and brings it all home as to just how horrible they are. Regardless of your views of 9/11, this video will definitely move you, and make you feel for the people who died on that tragic day.
