Rabble.com - more UGC Mobile Broadcasting

This is a hot category right now. Allowing people to broadcast content from their phone to the web. Saw it a few months back with the Juicecaster (www.juicecaster.com) and now its here with Rabble (www.rabble.com).

All very cool technologies, all very interesting, but no proven business model as of yet. Its only a matter of time before someone figures out what to do with these things.
