It seems every day there is a new video hosting site, video blog, video social network, or cool video tool popping up on the web. It’s tough to keep up!

So, to help you (and me) I thought it would be nice to put together a list of some great video sites that I find useful. Here are 20 of my favorite video sites. (Know of others? Please post them in the comments!)

1. Viddler - publish and watch videos. Great inline commenting feature!
2. Blip.tv - Publish your video blogs. Very nice simple player interface.
3. Veoh - video publishing, TV shows, and more!
4. Kickapps - Create your own online community. Great tools for sharing video, blogs, photos, audio, a forum, and more.
5. Ning - Create your own social network using video and more!
