You can never tell how these things are going to pan out until the uneducated marauding masses get involved and try to make some money out of it, so it is far too early to tell whether Knol is going to be a serious content provider or not. However, I am sure it won’t be long before academics are comparing Wikipedia and Knol pages. In fact as I type this someone out there is probably comparing two pages and hoping to make a bit of a media splash. Unfortunately I will have to wait for Knol’s ‘Webometrics’ page to appear before I can make a comparison with any sort of authority.
One last point. As Danny Sullivan emphasises, this time Google’s product is known as ‘Knol’ not ‘Google’s Knol’. Is this an attempt to hide the Google brand as we begin to suffer Google fatigue?
