The 1 Percent Solution? in Clickz.
The most important line in this article is one the author glosses over: “There’s nothing wrong per se with charging for online content, provided you charge for the right things and do so in the right ways.”
The article then goes onto dissecting sites such as Salon, which charges users to not see ads, which is entirely counter to the basic ad-sales model, which asks for a definable viewing audience in order to proffer an effective purchase.
Still, an interesting read, and one worth considering for us media folks.
