@mudge I _adore_ iA Writer, and use it for 90% of my general writing. However, it doesn't currently recognize its own sister product's markup yet (e.g. iA Presenter) or work well with variants like #Markua or #GitHubFlavoredMarkdown. That sometimes forces me to switch to a very customized .vimrc so I can tweak the markup, but that's (perhaps) a nitpick.

Between #iawriter, #vim, #Marked2, and #PanDoc I get all of my #WYSIWYM writing done faster. Thanks for sharing your process!
