Not a fan of the theory bubbles exist in a form worse than before, if at all. It's pretty rediclious to think people in small towns are in worse bubbles now. And to be frank same goes for big cities. Would need a lot more proof. Do you think acceptance of gay marriage and pot reform has been made worse by these new 'bubbles'? If they exist it should have been.
I would say we are far better off, but there is a 'thing' slowing down progress at an even greater rate.
And propergander is far more effective, but I see this as a separate issue.
