I am one of the core developers of the MoinMoin Python Wiki Engine (also used here).
Soon I began hacking the MoinMoin code and thus fell in love with Python, too. Felt a bit dumb, though, and asked myself why I didn't use that great language earlier (I coded in quite some different languages, but Python beats them all).
I usually hang around on #moin IRC channel on irc.freenode.net, so if you need any MoinMoin help, feel free to contact me there.
My (mostly german) wiki homepage is at ThomasWaldmann.
