Over at Dymaxion World, John has written an excellent rejoinder to "The Long Emergency", the Rolling Stone excerpt on the apocalyptic world an oil crash is about to bring. The oil crisis is bad enough without going into full on scare mode, so I highly suggest you read John's more balanced portrayal. For what it's worth, I've been looking into these things pretty heavily lately, and John's view strikes me as closer to the truth, but I'm still no expert, so take my recommendations with the proverbial grain of salt.
So long as I'm linking to excellent piece, go read Matthew Holt's myth-busting comparison of the Canadian and American health care systems. Great stuff.
