About three months ago, I asked for help improving the website design. It's taken me a while to follow up on that, but I finally managed to, and just put the new design live.
The design was kindly contibuted by @benjamin of Atlassian. I think it's a giant improvement over my original attempt. Many thanks! (Note that on a few points, I adjusted his original design, so if something is awful, that's likely my fault, not Benjamin's.)
I still didn't get around to writing of more documentation and copy, so the text is largely still the old stuff. That's going to be one of the next priorities.
Any testing of the new website is much appreciated. If you run into something broken, comment here or open an issue on github.
