not that this is the place for this, but while graffiti is "vandalism" it is also many different things to many people, and in different countries and even this nation it takes on a variety of forms. its awesome that there are new writers coming up and it shouldn't be discouraged but it is a pain in the ass to see all of the attempts at writing the new jacks are doing.
having contributed to dissing and being dissed at chill HOF spots, I can say that regardless of who went over who, it is bad policy to "TAG" diss, or rag someones work. This only contributes to other shit being dissed at that spot, and eventually makes the spot fucked up and hot. Instead do a burner or at least make an attempt to burn them. angry and buck make good points, but I seem to remember a wall that had ran for a while and was burned yet it was still ragged because of some odd reason by the same people. My point is beef is easy to start but what are the reasons? and if its a piecing spot and you get burned? burn back or outshine that person. fuck it tho, there are no rules so do what you will...
