I started using Ikiwiki as a way to replace Trac when using Monotone. Version control has been an interest of mine for a while and I wrote most of the ikiwiki monotone plugin. I'm not actively working on the Monotone plugin any more.
Lately I've been using Ikiwiki for other things and seem to be scratching a few itches here and there.
I generally use my openid login when editing here: http://www.cse.unsw.edu.au/~willu/ or http://www.google.com/profiles/will.uther.
I have a git repository for some of my IkiWiki code: http://www.cse.unsw.edu.au/~willu/ikiwiki.git.
