Hell, there are still plenty of alleys you do not want to walk up after the sun goes down but it isn't what it was. There are people out and about and while there is justifiable concern over the effect of such artistic gentrification (several visiting artists commented on it to me in 2011), the area still seems to have, in some ways maintained its former character while becoming a bit less "stabby."
The art itself reflects different strata of society. There is some that screams "high art" and others that hails to old school street art and still more that is simple, old fashioned advertising. Garbage cans, polls and posters all contribute as do "off the rack" decals (which some may regard as street art cheating).
