If people are more active in their music selection (which seems to be the case) then playing music at people as a concept, is on borrowed time. It's a shame because since that's what people think of as radio, the personality of it is mostly gone. With all that being said, internet talk seems like it could be endless in its variety & reach. In a decade, who knows where it could be? It seems almost assuredly light years ahead of what we have now.
