Confluence is... okay. I think Atlassian have successfully managed to sand down a lot of the sharp corners on older wiki-type packages that tend to act as a barrier to the non-technical types - from my perspective, that seems to mean that my non-technical colleagues can be persuaded to contribute to documents held in Confluence markedly more easily than to contribute to a MediaWiki instance that we previously had. So, while Confluence itself as a piece of software makes me grumble more often than not, I'm more than happy to trade that off against the easier sell to others.
