To change, or expand on, the question a bit...
Is there a larger issue with the grid culture in general which needs to be modernized?
Rather if grid girls are meant to attract fans then why is there a lack of fans on the grid? Instead we get the old rich guys, politicians, celebs etc. By design its a tradition steeped in exclusion as opposed to a more inclusive culture that most people now days require... a sentiment which I suppose is at the heart of the grid girl debate?
