I would improve the opening page text. I think it would be good to add some type of improved call to action. Also would like to see a bit more detail about what features are offered. Maybe a bullet point list like -Video, -Pictures, -Blog etc. One other thing I would try to implement is the ability to check out the site and user profiles before you actually sign up. It gives the potential user a much better idea of what he is signing up for. Good luck and keep us posted on the project. Might sign up later and give the site a test run.
