You guys are slow! Conservative pundit Rachel Marsden has already penned roving Wikipedia cofounder Jimmy Wales's first biography on Knol, Google's write-it-yourself compendium of articles. "And it will be a closed collaboration," she adds. Unlike Wikipedia, Knol lets an article's initial author control all subsequent edits. Other contributors can write their own articles about Jimmy, but Marsden's prank hints that Knol fights — in which multiple people attempt to author the definitive entry on a topic — will be a lot more fun to watch than re-re-re-reversions of the same old Wikipedia page.
