I've enjoyed wiki software since Ward Cunningham created c2. I'm mostly involved in deploying and advocating for wikis if I can help in that way. I was just starting to write an integration between mediawiki and drupal, but my computer drive got corrupted and I haven't found time to restart that effort.

Here is an audio of the presentation I gave about MediaWiki (Boston PHP Meetup, January 2009 at Optaros) http://www.archive.org/details/collaboration.at.wiki.speed-audio-part1 My wiki is at http://freephile.org/wiki/
