When I am dead, I hope it is said;

The Worldchanging blog is on my regular reading list - more so these days than boingboing, at least in time I spend on it. I can recommend the big huge _Worldchanging_ book that I read last month. I saw Charlie Stross' original post, and my friend David of the Eluminati made a similar argument recently, at least in the terraforming Earth is easier than terraforming Mars. I like the idea from the approach of refining the technology here before trying it at the end of a very long and unidirectional supply line.
