This is cool, but why would I want to draw diagrams like this? There's a plethora of tools out there that make drawing diagrams pretty simple, why do I want to do it with text? I'd drive myself crazy - every time you change one character in the diagram, you have to shift all the other characters on the line.<p>I don't mean to be condescending, but.. whyyy? It just seems so fragile to be doing complex diagrams in plain text like that.
