Perusing my paper over lunch, I spotted a nice write up of the project in todays Guardian.
Highlights : "perhaps one of the greatest testaments to the generosity on the web" "What makes the Wikipedia so compelling - and this article so hard to finish - is the way everything is so massively linked. You read one entry, and before you know it, you're reading up on Anne Boleyn or Italian greyhounds."
