I think Rush may've helped in the online evolution. He was the first media person I ever heard who interacted with his audience via e-mail.(Compuserve at the time) He repeated over and over that a computer was the most mind expanding step you could take in your life, and a guy like me who couldn't even type, was motivated to get a computer
One of the most stupid corporate decisions I've ever seen in my life was Apple's decision not to advertise with Rush. He is one of the true Mac Addicts and at the time Apple was struggling.
That's not surprising considering that the political philsophy of Apple's Board of Directors and Rush Limbaugh are often polar opposites.
