Yeah, our blog is currently a pain to work with in a few ways. It's generated straight out of our source repository from Markdown files, and you have to do the full pull request, merge, deploy to get posts out.
We're looking at moving the blog to another platform, and usability review will be part of that!
I recently wrote a blog engine that's pretty lightweight. Sort of tries to hit a middle-ground between a static blog and a wordpress type of thing. It also . . . doesn't work perfectly. I fucked something up with drafts, and I need to get back to it. But if you are interested, it's not too bad. Insanely fast.
