I spent a good couple of years working with UML and related tech and products (especially from the Rational suite). Besides the fact that I hated it, a big personal gripe I had with it was that noone looked at the UML after the initial review. Ever. We generated the diagrams to fulfill some outdated legal requirement (Sarbanes-Oxley, I think?) for getting listed on a particular stock exchange, but other than that they literally served 0 purpose. It was a massive waste of time and energy. Having said that, the sequence diagrams were quite useful.
