Agreed. In a couple of recent threads, it seems like "yuppie" is being used as a pejoritive for city people. In any case, it's clearly inappropriate here.
The whole article is borderline inappropriate: "The exact number of people taking such steps is impossible to determine, but anecdotal evidence suggests that the movement has been gaining momentum in the last few years."
It's a filler. A New York Times article? Barely. It's entirely reprinted from the Associated Press. Internet link? Peak oil. Some AP reporter had an off day and an article to write, logged into a catastrophist website, and let his imagination take over from there. No facts & figures on how many people and where. And the "movement" he's talking about is a movement back to the land, not a yuppie movement at all.
Bladeforums has a policy, more strictly enforced is some forums than others, that an original post should contain a reasonable amount of though-process on the part of the poster. This would have avoided a few of these pitfalls, instead of a link and a quick misdefinition.
