To be clear: if @simonbrown's C4 ends up leading to a renaissance of models with well-defined semantics, I'm all for it

I'd also say, as with all languages, there is a specific vocabulary for a specific crowd; meaning: some diagrams won't be helpful at times

whiteboard+marker or paper+pen as UML tools do not suck (that much)
