As noted in Business Week on December 14, 2007, Google has invited a select group of 'authorities' to write authoritative articles, to be called knols, on a wide variety of topics. Google's driving idea is to create an on-line reference source that competes with wikipedia as a first go-to source for reference knowledge. Instead of a 'neutral' wiki, which can be endlessly modified by a community of readers, knols will have a single authorial slant, much like an entry in a standard encylcopedia.
Rumors are floating around that there will be opportunities to comment and initiate dialogues about knols. So maybe the knol will evolve as a genuinely new form of reference material that takes advantage of the best features of traditional published reference (authorial credibility) and the web, including next-to-no-cost space and storage, and community interaction.
Here is Google's post on knols, from VP of engineering Udi Manber, from December 13, 2007:
Earlier this week, we started inviting a selected group of people to try a new, free tool that we are calling "knol", which stands for a unit of knowledge. Our goal is to encourage people who know a particular subject to write an authoritative article about it. ...
The key idea behind the knol project is to highlight authors. Books have authors' names right on the cover, news articles have bylines, scientific articles always have authors -- but somehow the web evolved without a strong standard to keep authors names highlighted. We believe that knowing who wrote what will significantly help users make better use of web content.
The worry, as many commentators have already noted, is that Google the search engine may slide into ranking knols above other reference sources such as wikipedia, essentially driving web trafiic to itself!
