When I was in uni recently I was learning UML and wondered why all the FOSS tools for UML sucked. I quickly worked out it’s because no foss programmer actually uses or cares about UML

It would be difficult to do really anything with such a pole.

UML is the virtual thing, so it will be a virtual pole, of course.

Sure they would. As a widely recognizable set of boxes and arrow shapes, it's useful for the kind of doodling that you might want to show someone else later :).

Challenge accepted.
