Google's homepage goes black to publicize Earth Hour!

From this page:

We believe in doing our part to help combat climate change, and found the Earth Hour initiative to be a timely, important event.

We applaud the spirit of the idea, but our own analysis as well as that of others shows that making the Google homepage black will not reduce energy consumption. To the contrary, on flat-panel monitors (already estimated to be 75% of the market), displaying black may actually increase energy usage. Detailed results from a new study confirm this.

I think it would also be a nice gesture if Page and Brin were to ground their personal Boeing 767 for Earth Hour, since it reportedly burns about 1,550 gallons/hour.
