Optimize image assets
I know that the repo is currently having some issues due to the size of all the static assets. I wonder if there is interest in running an optimizer (such as pngquant) over the existing image files. My own tests indicate that this could reduce file sizes by 25-75 percent. It would also reduce server load.
The downside is that this would mean storing a very large number of binary diffs in Git. There are ways of rewriting history to avoid this, of course, but that would break everyone's forks.
