I promise we do it in whole new different way of sharing. YOu can follow TV Shows, NBA, Movies. and share the events that are the most interesting to your friends. So you will get recommendation of what to do from friends. Like for instance I got a recommendation that 2 1/2 are airing next week
We tried to have a more thoroughly describing landing page. But believe me, this product you will get more with just a few sentence than if we described it with a 100 words. If you use the product, i.e. if you log in you will understand it immediately. That's also why we will make a demo video as you suggested, but we can't just afford it.
We had a regular sign up form before. But we thought that: Why shall user's create an another social graph, when you have facebook? it takes maybe months even years to get your 100 friends on a new app. That's why we choose to have facebook. Though we will consider other login alternatives in the future. Right now only choice to login is with facebook.
