Cyber Graf?

From this week's New Yorker:

"The graffitist's impulse is akin to a blogger's: write some stuff, quickly, which people may or may not read. Both mediums demands wit and nimbleness. They arouse many of the same fears about the lowering of the public discourse and the taking of undeserved liberties."

Thought it deserved quoting here. It comes from a profile on the British graffiti artist Banksy (the featured work was done on a security fence in the West Bank).
