I just started working on a similar project for the exact same reasons!

I think your site looks good, but I would definitely try to make the Pocket logo stand out a bit more. Pocket is your brand, be bold with it. Second, I would replace the "Sign up now!" button with the two actual forms needed to sign up. Not having to click through could dramatically increase registrations.

I'll leave more comments once I've had time to use the application.
