I'm just about to switch over from MovableType to GitHub Pages http://pages.github.com/ . They use Jekyll http://jekyllrb.com/ to publish text, HTML or Markdown. So far it's pretty awesome.
The benefits of this particular setup include:
* all articles are under version control
* just do a `push` to publish
* easily run a local Jekyll server to preview articles
* use a real programmer's text editor (not some web form)
* Markdown is the best for tech articles
* write, preview and commit while offline
* code syntax highlighting
* integration of snippets (gists)
* variable layouts for different page types
* pages are static so are served fast
* easy to add comments with Disqus et al
* easily port your content anywhere
* keep images and other binary content alongside text
Which reminds me - dear $DEITY, when is HN going to support Markdown?!
