Also, if you haven't seen this submission, http://news.ycombinator.com/item?id=2061359, I would recommend taking a look and trying to learn what the founder of that site did and the lessons that people take from it in the comments. Basically, faking a lot of user content is important. This ties back into the first point I made about seeing an example. I'd love to see some of the 'leaders' and their top recommended movies list. Maybe if some leader had a lot of the same picks as me, I'd be interested in signing up and following them. Otherwise, how can I know that I won't be the first person on the site? Showing that you have users (even fake ones) on the front page makes it seem more like a place I would be willing to spend time.
