I love that experiment of yours! I've found in your bookmarks that one on emacs and I thought to myself "hey, I never really tried emacs". So thanks to you, that's what I've spend most of my time on for a few days now!
Thanks. I've been using Emacs for years, because it's actually a better text editor than the joke about it being an operating system suggests. At least for composition. Nothing beats vi for precise revisions. :)
However, I think I'm going to go back to HTML with m4 macros. But instead of writing posts in HTML, I'll write them in Markdown, run them through a converter and pipe them into the clipboard, and then paste text into my page.
