The Myth of Crowdsourcing - Forbes.com

There is no crowd in crowdsourcing. There are only virtuosos, usually uniquely talented, highly trained people who have worked for decades in a field. Frequently, these innovators have been funded through failure after failure. From their fervent brains spring new ideas. The crowd has nothing to do with it. The crowd solves nothing, creates nothing

Interesting article that challenges the conventional wisdom of Crowdsourcing. The insight is that the well known 95-5-.5 rule (where only .5% are actually contributing content) is actually the key dynamic that governs so called crowdsourcing applications. I like the framing as "broadcast search" to find "virtuosos" who then contribute the main content and then allow other "curators" to modify and edit the content.
