DanceJam : Learn Dance Moves from Pros

Do you like dancing? Want to show off your moves or pickup a couple of new ones? Enter DanceJam. Here people can upload and submit their dance videos for others to see, comment and vote on. One really interesting feature is the battle contest, where two dancers show off their skills and viewers decide who is the better dancer.

Features:

Upload your dance moves and see what others have to say.
Watch dance videos from others.
Watch dance video in full-screen and slow motion modes.
Browse videos by type (ex. lessons only) or popularity (i.e. most viewed, highest rated etc.)
