Here's the quote that I read out loud during Innovate Publicity Now: "Word of mouth is key to the movement's success, Pure Evil Says: 'Street artists are more aware of the art marketplace now. But it's seeing what everyone else is doing that makes you want to step up your act. We're not doing it to be accepted by galleries but by our peers. Street art doesn't rely on reviews; there are no tastemakers.' Instead, he says, the internet is best for spreading the word: 'If someone does something brilliant in Sao Paolo you can see it days later in London.'"
