I thought I would let you know that I have been advocating the textual approach to UML modeling, which the OMG itself issued a specification about in 2004. In my Software Engineering course, I advocated both PlantUML and your site, PlantText, as relatively speedy and stress-free alternatives to diagramming. Visio was making me constantly enable and disable glue (and usually disabling snap) so that I could avoid constantly undoing its failed intuition. This is great.
