The thing with Atlassian's whole stack, I've found after nearly 5 years administering them, is that how the users perceive it depends entirely on how it's run.

The thing with Atlassian's whole stack, I've found after nearly 5 years administering them, is that how the users perceive it depends entirely on how it's run. That applies to nearly everything they make, Jira, Confluence, the whole lot. It's possible, and very very easy, to set up a shitty Confluence wiki, and some of the details of its performance are not exactly obvious. It takes a bit more work to set up one that's both well liked and easy to use. If I had it to do over again, I'd still pick Confluence over MediaWiki every day of the week and twice on Sunday. Life's too short to deal with wiki markup by hand.
