Hi Mike,
I tnik you have some really good ideas. I would love to hear your take on muzui.com, a site that I co-founded. We build the site as free mobile games with all the features of a web 2.0 social community. Our "main attraction" is that we have created a level editor, so that the user can create their own mobile games (they also work online). As I said, I would love to hear your take on it?:)
