I see a lot of people bashing Confluence here.. may I ask why? Having used Twiki, DocuWiki, MediaWiki, and now Confluence; it has become my enterprise wiki of choice. If you can get over its J2EE requirements which make for a huge PITA when the time to upgrade to the next version or make it work with other J2EE applications on the same Tomcat instance, it's a pretty productive tool. It gets the job done, its straight-forward to use, and performs quite good. Can I ask why there are a lot of disenchanted Confluence users out there?
