WikiText
I don't know about everyone else, but I prefer to use a markup scheme when writing rather than a WYSIWYG editor. It's just that I prefer to see the layers behind the presentation. So, I've abandoned the WYSIWYG editor I had been using and gone back to Textile. Alas, I've also been using WikiText and I've found I prefer that system to Textile. All I have to do now is to find a way to get WikiText working here.
