I like your website and what you're offering is really cool but I think it would be better if you specified how you much it costs or if there are any limits. I understand it's in beta and maybe you don't have pricing figured out yet, but as a potential user, I'd like to know more before signing up. "Create a free account" with no pricing page is scary. It tells the potential user nothing. I'd rather have "Free while in beta" with an explanation of future plans/pricing and limits. Otherwise, it looks really neat.
