Pretty much just what it sounds like, LanguageTube.org is a place to learn languages with YouTube videos.
Currently, videos are available for the Chinese, French, German, Korean, Russian and Thai languages.
The site has not been updated for a while, but let's hope a little web traffic will re-fuel the motivation to bring together language videos from all over YouTube. It is a great idea, and currently the site it totally ad-free.
