Can You Make My Home Page Smaller?

I like the design of my blog. I especially like that every post I've written shows up on the home page, without having to page. Of course, that means that the more I write, the slower my home page will load.

I've tweaked things out a bit, but I've reached my HTML limits. Can you help?

Since the bulk is repetitive, I realize JavaScript could be leveraged. As an extreme example, the href could be omitted and generated via JavaScript from the title + date. But this has accessibility problems, so I'm not too keen.

The page is pre-generated by Jekyll. You can see the source on github. But, just view-sourcing the page should be good enough. Can you help?
