Looks good to me, it depends on the quality of the content. Will you make the content or have some sort of moderation to guarantee a high quality ?

Yes, we want to have a heavy moderation system. We will only approve high-quality content.

In fact many try to get a winner startup. I see a flow of online intensive startups, think in a way to connect people in the real World. Try to see this way, instead to get people from the real World to the online World, look the other way around.
