Having Vi burned into my muscle memory since the 80's I could never use (literally) emacs for more than 30seconds without inevitably random "i"'s, some "/regx", etc embedded in my text - (that and the RMI inducing ctl-meta-esc-alt-x'ing thing ;))
I love Jekyll/Octopress - but my tool chain of choice for post writing is...
IA -> Marked -> jekyll/s3cmd with a tripwire script -> s3 -> cloudfront
Write - save - blam.
