I agree. That was my first reaction and I suspect most visitors will be in the same boat. I like the simple design of the landing page and in the context of a hackernews visitor, I might click through to see more of the project. I almost certainly wouldn't signup in the context of being a potential customer.
Also mention more about the themes and the level of customization I can do on my blog. That would be super helpful. Keep up the good work, you awesome creator.
