I kinda get what you're doing, but a screenshot or infographic would quickly communicate if it was worth the user's time.

I'm not sure whether I think a big "sign up" button would be better than the two big form fields you have from a conversion POV... But it'd be easy to measure/test. Given most of the big boys have a signup button, I assume your way would convert less well.

Having a different color for strong tags is a bad idea. They look like links.
