I'm a big fan of octopress now, which is just jekyll with some rake tasks and plugins already set up to make things even easier to get started.. https://github.com/imathis/octopress
I can attest to doing the same. Now i'm on jekyll+S3 and haven't looked back - it's great! Having said that, the jekyll posterous image exporter i couldn't get to work. But i don't post many photos so that didn't worry me.
then with jekyll you can host your blog as github pages - this, to me, seems like the best option to anything that is out there.
