Graffiti as Art?

Graffiti has always been around if its in stylized letters, or just a simple portrait and there is still a struggle where some might say graffiti is not a form of art. The way i see it, you can  learn a lot from a person from just looking at there work or tag. It can show the way they lived or what kind of person they were, hieroglyphics can be an example because they convey a message or a story for other people to discovery. Besides the risk behind graffiti, artist tend to go the extra mile because you can learn something new about yourself or just think of your next masterpiece. Every form of art has a story to tell, whether if its in a gallery room or a wall on the street there is always a purpose for the art work to exist.
