Hmm, interesting. Finally been playing a little with Markdown, and am pleased with the initial results.
Here you can see a sample current page and the new version after putting the text through a) html2text.py and b) Markdown. I'm currently losing the bold and italics for some reason, but the overall look is the same.
Tables are different, as they're unsupported by Markdown. Here, for instance, is the current Markup Matrix page and the ugly new one. I'm thinking of either writing my own parser for tables, to run after Markdown has run, or just not using tables in my pages, or just placing them in a "pre" marker. We shall see.
Note for archive: look and feel of the linked pages are in flux, and may well change at a later point.
