Salon.com has joined with former AOL chief Steve Case's micropayment company to offer $10 in actual money for users of Open Salon to tip generators of content. The idea is to extend this principle indefinitely --- in essence, to have users pay for user-generated content --- through Case's Revolution MoneyExchange service.
It will be interesting to see the results once the free ten dollars are gone. CNET's story on the idea is here.
