Great idea with a lot of potential.
I'd strongly consider a complete from-the-ground up rethink of the new-user flow. This may sound harsh, but I'd argue that as the site exists now there is no clear new-user flow. There's no concise path through what's being presented.
If you're stuck, a good exercise is to go grab 5 people and show them the site. Don't explain anything. See what they do. See if they get it. See if they interact with it the way you expect a new, fresh potential user to. (In effect this is what you did by posting to HN, and we're probably a big chunk of your target.)
To be honest, I didn't even try the service because I'm not sure what to do/click:
1. There's no clear call to action other than the red "create your page now" button, which I'm not going to click if it requires an email address/website, when I don't understand what I'm signing up for yet. "View a sample page", "see demo", might be better.
2. The most prominent thing that jumps off the page visually is "$9/mo". I think I understand that you're selling a value-added service (which is good), but why don't you hook me on trying the service for free, or pitch me a great demo before showing me dollar signs? Seeing the value-added pitch at the top and in prominent color, before I understand the service is a clear path to my browser's back button.
3. "try it free for a few days with no obligation" isn't comforting. What happens after a few days? Is the basic "here's a pretty landing page for your soon-to-be-built site" a free service indefinitely? It's just not clear.
It's as if you need to step back and consider what one simple goal is most important to you for a new user landing on this site, and then strip away everything that doesn't directly support that. To paraphrase some quote: "perfection isn't achieved by adding, it's achieved when there's nothing left to take away."
I hope the comments here will prove helpful (and not too harsh), and again, great idea. Good luck with it.
