I love it. Even with GML, you run into problems. Diagramming is an art more than a science. You have to know your audience (technical people, marketing types, investors, customers...)

Leaving stuff out is also important. (Example: Unless you're building a DNS related product, don't bother to include "DNS" in your diagrams. Your use of it is assumed.)

This is wonderful. Thank you.
