Social bookmarking and news site reddit today announced the launch of reddit.tv, a video sharing and rating service. The new site takes the videos which are recommended and discussed on the main reddit site, and features them in a more video-friendly setting.

The original reddit site, launched in 2005, lets users post links to content on the Internet. Other users may then vote the posted links down or up, causing them to appear more or less prominently on the Reddit home page. The site also allows discussion of individual topics or links. Users who submit articles which turn out to be popular with users like, and who also “vote up” receive “karma” points as a reward for submitting interesting articles.

The new reddit.tv site features its users’ most recommended web videos, with broad categories like “geek” and “happy” for browsing, in the old “most popular” standby (like this “hard drive clock video, at right). They have also partnered with the TED conference to specially feature videotaped talks from that event.

Also, the new video site now has integration with Twitter, to pass along links to videos, “generat[ing] a random sentence to make you look awesome without even trying.”
