Wikipedia vs. Knols

From: Google Knol: Self-Interest not Community from Transparent Office by Michael Idinopulos

Wikipedia's quality is high precisely because there is a core community that cares deeply about it and ensures that crap is detected and eliminated. Google Knol isn't likely to generate that kind of committed community. As a result, it will probably come to look more like the blogosphere: Tons of content, some good, a lot of crap.

Google's solution to the quality problem is, predictably, technology. Feedback ratings are a central feature of Knol's design, and Google is almost certainly working on search algorithms that incorporate user ratings, not just at the asset level (i.e., article quality) but also at the author level (i.e., personal reputation).

Will Google's self-interest-plus-technology model trump Wikipedia's community model?
