it is a fact that most graffiti is meant to be a message of some kind to the people. it may be some useful message or just crap. when people paste posters on walls, its their way of spreading awareness. graffiti is just another way of spreadign awareness that some people prefer and its left to the individual to either accept is as art or reject it.

There are the people who say 'Vandalism! It looks shit!'. They are the type who could see a Van Gogh piece on canvas in a museum and think 'Wow! The brush strokes, this is amazing, so beautiful!', then see it on the wall outside and turn their stuck-up noses up at it.

Then there are those who say 'Both, it is a piece of art which is inappropriately placed on someone else's property'. These people are smart, open-mined individuals who know what they're talking about. Some may say 'Yes, but what if its badly drawn', well as you probably know art is based on opinion. I for one think Picasso's drawings look like shit, and wouldn't pay £5 for one, but there are people who are prepared to pay millions.
