Idea for improvement: show the webpage creation interface without needing signup. I want to see what it's like to use without making an account. I won't bother with sites which immediately ask for login. This doesn't have to be an interactive demo, just screenshots are fine.

I suspect I'm not the target audience anyway. I'd rather write a custom Jekyll theme and use git to publish with the GitHub Pages push hook. This sounds like it's much simpler, maybe something like the Blogger interface.
