I just deployed 1379be9 which refines the feed a lot more.
I use a separate compiler for the feed that doesn't generate the table of contents (that doesn't seem to work in the feed readers I used anyways) and doesn't use Pygments for syntax highlighting (in yoleo reader for example, pygmentized code blocks were completely missing from the feed). The separate compiler avoids the use of MathJax as well.
Quick testing in yoleo reader leads me to believe it looks nice, probably as good as it's gonna get I suppose. Hope it works well, if you have any questions/suggestions let me know.
I'll probably write a post about it tomorrow.
