ZozzyTV, my Startup Launches

The idea is to allow people to upload their video, which is then displayed on 3 huge screens in Dublin city centre (Ireland, each one is the size of most shopfronts). Any feedback, comments, suggestions? Its been running for 3 days now, and content submissions are just beginning to pick up. Theres a version 2 of the website going to go live in the next few days, so I would love some feedback so I can work in anything badly needed before then.
