The problem with this model is that the mental transaction (do I care enough to pay for this) is more expensive than the couple of cents it costs for access.

A similar problem exists when trying to decide to pay for an article from a journal you don't have access to. Is the abstract compelling enough for me to fork out $100 dollars for this article? What if the abstract was misleading? Can I return it?

As a consumer, I'd rather just pay a higher flat fee for internet access / browsing and have that collective wealth distributed to content providers based on some metrics. Better content gets bigger portion of the pie. The problem is probably determining the metrics.
