Welcome to Dublin

I love street art. I enjoy nothing more than finding a cool new "installation" around town and home or while on holiday.

In Ireland I have discovered, much to my incense, that in Ireland people like to grafitti street art. Has street art now become so mainstream that anarchy is only achieved by defacing it? Is unsanctioned guerilla art no longer considered provocative? Or are the knackers just too dim to get it?
