The Week: Media news - Google sets up Wiki rival

Google is launching a new online information website to rival Wikipedia called Knol.

Entries on the service will be written by people with particular areas of expertise and will include bylines, unlike Wikipedia, where contributors remain anonymous. If an author includes an ad, Google says it will offer a share of revenue from the ad placement. Separately, the former Google staffer Anna Patterson and her husband Tom Costello have launched a rival search engine called Cuil.com, which claims to index three times as many pages as any other search engine.
