If you don't need tagging (as http://danluu.com/ doesn't, for example), you can use my "no workflow" solution:

* draft in markdown

* render in HTML (using any Markdown to HTML tool, e.g. pandoc)

* link your CSS in the HTML file.

* push to your preferred serving platform

This has the advantage of getting you started as quick as you can open an editor.

If after 5 posts you are wanting a tool, pick whichever (Hugo).
