In the world of free wiki software packages, MediaWiki is more well-known, but DokuWiki is trying to close the gap. The Internet Techies site indeed lists it as number 2 and and many people feel it’s easier to use and more effective for many sites.
You can see here on Slant that in answer to the question “What is the best multi-user wiki?” DokuWiki came out #1 and MediaWiki #2.
