The PeakOil.com website is down. Aaron, the webmaster, indicated that the service provider got "fed up" (paraphrasing) with the resources that the site used up. I also got the impression that many of the archival material disappeared. Too bad; Aaron and the volunteer moderators put a lot of hard work into the site.
Goto Peak Oil Community for an alternative message board.
Update: For another Peak Oil fix, Matt Savinar has temporarily (i.e. the stretch political drive) made available a downloable copy of his book in PDF form.
Or excerpts from the book Blood and Oil: The Dangers and Consequences of America's Growing Petroleum Dependency by Michael T. Klare.
