I respectfully disagree. We have very, very few scantily clad women on our top list. Spend a bit more time on VS and you might find that it's the community there that sets us apart.
You're right, it is all about the community. Please have a look at VideoSift. We are also "holding our own" with the other video providers mentioned above - however we do not host any video. We are a video sharing community with voting, tags, commenting, contests and other goodies. We don't get a lot of love from the mainstream, but we are growing rapidly, and it's all thanks to, and about the community.
