I work for a Fortune 50 and we use Confluence. For us it works well, because we have more teams here than I can count, and people move between teams (and teams move between business units) all the time. So the standard rule is that if you build something, you are expected to document it in the Wiki.
About the only downside is that sometimes documentation gets outdated and you have to hunt down the current version of a process, but that beats the alternative, where nothing is documented.
