Today Twitvid announced that it is launching a new open social video network and redesigned site focused on helping users find their favorite videos. Twitvid wants to make it easier to upload clips and share them to YouTube, Vimeo, Facebook and Twitter.

For now, Twitvid's frontpage interface looks more like Digg's (before the social newsrooms). It shows most popular TwitVids by views, along with a featured Twitvid and a Twitvid Tuesdays Winner. There is a list of popular members on the right rail. Twitvid is tossing this simplistic design for user profiles that focus on personalized video taste. Sharing will be more focused around personal interests rather than top rated content. Imagine the Facebook news feed, but only populated by video that has been personalized to your tastes.

Twitvid will also feature channels organized around specific interests.

Twitvid has seen its user base grow 100% since last year. Currently there are more than 12 million unique visitors. Twitvid launched in May 2009. We first wrote about it in July 2009, back when it was a a brand new iPhone app for uploading video to Twitter.
