Hi, thanks for letting us know about this project.
I read through the design document, and there's definitely a lot of
good ideas in there. I particularly agree with the list of questions
the new site is supposed to answer, especially with regards to new,
perhaps non-tech-savy visitors.
I just mocked up a little live demo of what I could imagine the new
homepage to look like with regards to the points discussed in the
design document.

I'd really like to contribute to this project, and any feedback on
my proposal is very appreciated. A summary of my specific design
decisions and why I made them will follow shortly.
