This is exciting. If you can get groups of people to collaborate on topics of shared interest then you could build dedicated pages ("information hubs"?) for every conceivable topic, sort of like wikipedia, only better. Then advertising would pay the bills (and probably very well) because those hubs would be linked to often and come up frequently in searches. To build momentum you could crowd-source by offering users a cut of the advertising revenue depending on their level of contribution.
