Paid Content: Post-Pricing: Is It Crazy Enough to Work?
Post Pricing is a new payment system where "sellers provide items (information, goods, services, etc) to buyers before a price is set. Buyers use those items, decide a fair price, and then pay that price."
The system was invented and patented by Thomas Murcko, founder and CEO of WebFinance Inc. You can view a Flow Chart of the system here.
The interesting part of this, and why it might even work, is that buyers are given reputation ratings based on what they agree to pay for content. The system then allows content providers to define the level of buyer reputation to which their content is made available.
