While it's not a perfect match to your question, YC has been putting out so many amazing videos during Startup School the past few weeks which you might want to check out if you haven't already. For example:

Just like self-help books and CEO advice, taking career advice from engineers, even great ones, is a waste of time. It is useful to read for entertainment value, and to be well-read in general (like understanding history very well in order to understand modern politics), but taking direct advice would be foolish.
Perhaps that isn't the intent of your question but just wanted to state that, at least as a warning to others, as it is the implication.
I'd put a call to action right below this text to potentially get more sign ups. To be honest though I would like to see what it is before signing up. I can't really tell what I can do on the site from the landing page.
FocusWriter, listed in the parent as a native Mac application, is open source and works on and has compiled binaries for Windows, Mac, and most Linux distros.
I would love to see how it was built. I'm quite new to web development, and I recently built my first sign up page, but have always wanted to learn how to build the nice animations that show up on many sign up pages.
Bitbucket offers free private repos to everyone as well. And there's no need to fill out a special form. That's what I've been using for school projects.
I would definitely move the call to action button "Get Started For Free" to be above the fold. It seems like it would go nicely above the "Digital Project Spaces for Creative Teams" section.
