On 15 January 2001, Wikipedia introduced the first online encyclopedia that could be edited by anyone, forever changing the way we seek expert information. While critics scoffed at Wiki’s accuracy and scope, Nature concluded in a recent study that it competes pretty darn well with the original pillar of accuracy, Encyclopedia Britannica.

An exciting development in this brave new wiki-world is the introduction this year of Green Wiki. It is certainly a welcome development in a thought-space where there are more questions than answers, and knowledge and experience are plentiful but diffuse. Here’s hoping that it will prove to be an equally able concentrator of all things green.
