Also on the way to the article via Google I came across this page on Ashtanga.com that I had forgotten all about. A real treasure trove of articles.
Here's a list of the articles they have (their page is the one to bookmark rather than mine, they've spent years compiling it.

The Yoga Bums By Rebecca Mead (The New Yorker, 14 August 2000)
