In my view one of the biggest problems of UML was that it's ugly and not very intuitive. For a while I jumped on the UML bandwagon and developed a lot of diagrams of the various types. Turned out that even very experienced developers didn't understand them not even to mention less technical people. Now I just draw a few boxes with arrows and usually get the message across. UML as code generator also made for really neat demos but in practice the diagrams for complex systems were harder to read than the code. If I had one wish it would be nice if there was a standard for embedding and editing diagrams in different software like Word or Powerpoint or the web. It seems you always end up copying/pasting stuff while often losing the original after a while.
