Looks good. I think I should point out that the current version of python.org is actually pretty decent in the scheme of programming language/codebase sites (there are some real eyesores out there!)
One of the biggest parts of this redesign is happening on the back end. One thing I look after on the site is the PSF board resolutions and minutes pages. Oh you see a typo in the latest page? Here's how you fix it:
Get to machine that has the checkout > svn up > edit file > rebuild website locally > run webserver and check local instance > svn ci > wait for server cron job to catch the change and update the live site > confirm on live site
That sucks. For me it's not unworkable because it's not far from what I do as a developer, but it's definitely a hassle more times than not. However, getting less technically savvy contributors is not very easy. We had an administrator who was tasked with updating the pages I look after, and this person didn't know what an SSH key was (not their fault). The whole thing became a non-starter.The new backend will continue to support the developer-like workflow (which really is good in some cases), and it'll support online editing which will be nice for a lot of things as well.
My 2 cents, I really like Nodejs's website. Closer to Python, I'm really digging the websites for the Pocoo packages (Flask, Jinja2 etc).
Let's just stay civil
