Blorgit: Org-Mode based, git amenable, blogging engine
orgmode.org
orgmode.org
I'd recommend just using the publish interface built into org-mode (see [1]). I use the publishing interface to generate both my home page [2] and my lab's wiki [3] (which runs off of a git backend using post-update hooks). These have the benefit of no dependencies outside of Emacs+Org-mode.
Also, as another commenter pointed out, org+jekyll works well.

The nice thing about spending the time setting it up is that once it's all done it is really quick to publish. All you do is create your post in org mode, Alt-x org-publish and then git push, and your post is live! I tried posterous before this, but getting all the syntax highlighting/formatting right was just a pain. With emacs + git, everything flows smoothly. In my opinion, well worth the time it took to set things up.
Thanks for the tip.
Be sure to install Ruby 1.8 (should be default option) not Ruby 1.9.
(and then I remembered I have nearly nothing to blog about anyway.)Much rather have something that worked like Jekyll or Hyde in doing static html generation.
