In a response to the new york times article on data center efficiency diego's weblog takes apart this New York Times article on data centers and power use. It looks as if the reporter James Glanz doesn't know what he's talking about. Even if he didn't start out wanting to make an "exposé" (however misleading or outright false), he ended up doing so.
What I find disturbing is that the tenor of Glanz's article is that the experts don't know what's best, and strongly suggests that someone knows better. It's an implicit, ignorant call for government regulation.
