The above image comes from a Ping Mag report on Sao Paolo banning all exterior advertising in a crackdown on graffiti.  I'm not sure how I feel about this.  First, is there a causal relationship between outdoor advertising and graffiti?  Second, is graffiti that bad?  I hate tags as much as the next non-gangbanger, but I love street art like this (if you live in Chelsea like I do, it helps make the neighbourhood):

I'm trying to picture New York without any ads - and i'm not sure if I like it (although they could drop the giant billboard by the Gansevoort Hotel).  It reminds me of an airbrushed photo I saw in a gallery in Toronto a few years back: the artist had photoshopped out all the brands and logos from the image.

(On an aside, my iWeb spellchecker doesn't pick up "photoshopped" as a misspelled word)
