Several of my ideas revolve around changing the focus of current online businesses. For example, this illustration:

is incorrect. Neither Priceline nor Accompany is a C2B (consumer-to-business) site. Priceline buys airline tickets, etc. wholesale, and often only after it receives a bid. Accompany does a similar trick, buying products in advance and then "auctioning" them off to consumers. Both of these sites are B2C, just like Amazon. The only thing they've reversed is the marketing spin.

A true C2B site was my original inspiration for ThoughtStorm v1.0  That site would have allowed individuals to post ideas for advertisements (print, radio, tv, etc.) that would have been bought and paid for by advertising agencies. That's C2B.
