I understand your sentiment. When it comes to coding, I pay attention to productivity because coding involves so many various tasks and cognitive switches that cause friction and block progress.

But writing, for me, is different. My primary progress blocker for writing is not writing. And spending time tweaking technology is so tempting, and so fun, and very much not writing.

I am, in fact, doing right now not writing, so I should get back to it. (Plain MacVim, using Latex as the markup.)
