Here's how Knol works. Experts in a given subject log into a Google account and use the Knol software to post an item, also known as a knol. In some senses, the process is like producing a blog post -- but in this case it's not something written off the cuff but carefully crafted to coherently explain a single subject.
One key attribute: Knols are meant to be signed with the author's actual name. With permission, Google will actually verify the writer's identity, either by credit card or phone.
"The process will take 20 seconds with credit cards," says Knol product manager Cedric Dupont. Phone checks will take a minute or so. This vetting, Manber hopes, will give knols accountability and, in the case of high-status authors, the benefit of a solid reputation.
