Now I'm a big advocator of markdown. I use it for nearly everything, even notes of gibberish but keeping a consistent html output seems impossible.

I use tmpvar's markdown previewer to write out most things before saving it to a file, most likely to be viewed later on bitbucket or github. The problem is github and bitbucket's html style is different and by quite a bit.

Hopefully some standardisation will come from standardmarkdown.com mentioned in the article.
