I believe most content creators that do make a living use a hybrid approach but for the average Joe, I hardly doubt paywalls are the way. Man, I was downloading shit on eMule with a 256kb/s connection when literally getting out of the house, going to the blockbuster, going back home, watching the movie, going back to the blockbuster to return the movie and back home was 100x faster than downloading the movie. IMO v4v is the way to go for average content creators, and that means you give the value first for free and then people gives you value back as they see fit. If the content is behind a paywall, then is just good ol' content selling.
