just my useless opinion on the self promo thing:
.01: it's graffiti, the whole point is self promotion, pushing your bullshit so everyone else who cares about graffiti will notice you.
.02: if you look at this site, you quickly realize almost everything on here is self promotion, very few people are posting lot's of pictures that aren't of their own work, primarily in the train section.
people need to quit all the shit talk about things they themselves do. you were wack one day, you posted your own flicks, you said dumb things, so ease up, you'll live longer.
