In other news, I decided to write my own wiki last night. I'm almost finished, as using apache mod_python, postgresql, and xml.sax makes it almost too easy.
Appended after seeing dyork's diary: I'm using XML to store the data in a neutral format, and I'm providing multiple front-end languages for editing it, so knowledge of Ward's format, structured text, MoinMoin format, et c., or raw XML, will keep you from having to visit TextFormattingRules, hopefully.
