I'm impressed with the design =). I like how the right column is used as a per page FAQ.

A few minor suggestions:

- Consider merging or ditching one of the two taglines. The site becomes easier to read if the eye doesn't have to jump around.

- When a user is not signed in, there are 3 buttons in the nav bar which lead to twitter login. It may be a good idea to remove them or add example content for guests.

- The "Get Started" link is really a "Log in" link. This could be confusing.

All in all, great work! Especially for a little over two months development time. I'm curious, how are you marketing the site?
