Thanks, that hits a soft spot in me. Like many programmers, I've wanted to learn about web design for a long time. Here, I really did the best I could, and am really happy to hear that it's not eye-achingly disgusting (to some).
I think you did a great job. Tells me exactly what it does, I don't have to hunt down screenshots, the call to action button is obvious yet not obnoxious and it's clean.
