I used to think this as well. But over time, I've seen it devolve into a wasteland of out of date information. This is driven by two factors. First, the search functionality is by far the worst search I have ever seen. This leads to duplicate information as people relearn and redocument things because they couldn't find them. Second, confluence has a very powerful permission system. Once you get past a certain scale, you can end up with little fiefdoms of information. Want to update a common piece of documentation? You need to convince the owner to give you edit rights. Who is the owner? I dunno, start asking around.
