Graffiti

I've got a question: Is all graffiti tagging? In other words, is it all
someone's mark, public signatures in some form or another?

I really don't know much about the various genres of this artform and tend
toward the more conservative "damn kids should paint a piece of plywood if
they want to be artists but can't afford canvas" school of thought.

As an outsider, it all strikes me as marking behavior, i.e. dogs pissing on
lamp posts. Which is not to say that I can't see its appeal. We all want to
make some kind of mark in the world, don't we? I'm particularly drawn to
stencils, and could see a younger version of myself going out and laying
down a few of them some summer nine-beer 4AM.

But like I say, my present self is a bit annoyed with that younger self.
