Demo not working for me. Even if it did though, I agree that you should make more apparent the immediate use that the site has for the new user.
For example, try this query:
Another thing that I found annoying is the 'please wait' screen. It plays around with my mouse cursor and gives me a 'forbidden' (circle with a slash) rather than the proper hourglass/waiting cursor that is appropriate for this situation. You might consider canning the 'please wait' bit entirely, or make it less prominent.
