You know, so many of the comments I read in here sound pretty much like "It'll never fly, Orville"... basically, insisting it will never happen, but without really knowing (or saying) why it can't.
Saying it won't happen because it hasn't happened yet, isn't an answer. Also, saying it won't happen because people won't like it, is not only not an answer... it's a response that has been proven wrong, time and time again, in multiple industries (for instance, the establishment of pay cable, the U.S. traffic laws, and the transition to CDs and DVDs from vinyl and VHS).
When, at the same time, there are examples of the phenomenon actually happening, and successfully, I fail to see the logic in insisting it can't happen.
So... where are we now? Are we discussing facts, pros and cons, evidence? Or are we just standing on opposite sides of the room throwing pies at each other?
