Is Google's gamble Wikipedia's nightmare?

Despite electric growth rates, the reference space hasn't attracted a ton of ad dollars with the ad-free Wikipedia dominating the field. But Google's decision to launch Knol could change all that.

What is Knol?

While many have called Knol a competitor to Wikipedia, it's certainly not the same thing. Unlike Wikipedia, Knol won't be anonymous. Instead, authors will be linked to their articles, something Google hopes will help promote better accuracy and in turn help attract wary advertisers into a space dominated by questionable content.
