I met Michael Weinberg from WizPerts at NMX Conference and was intrigued with his idea of setting up an experts community for any topic, not just technology. He is building a platform that will manage expert communities where the experts will be paid for answering questions. Payment is based upon the perceived value of the answer to the question asked.
