I think the article oversimplified and over-polarized things (as most popular magazines do), but I do think it had a few valid points, even if it presented them in a skewed manner.

I agree that there are poorly trained teachers out there and with the popularity of yoga, I'm sure schools have popped up that run teachers out on a conveyor belt system of training (if they show up and pay, they're gonna get certified, I'm guessing). Which is unfortunate for the good teachers out there who have to work harder to prove themselves, for the student who may have to sift through multiple teachers to find a good one, and for the aspiring teacher trying to find a good school amongst the crappy ones.

I also believe that there are some instances of people pushing themselves too hard in yoga and therefore doing more harm than good, but I think that has to do with the western mentality of "feel the burn then push even harder!" America tends to do everything to excess, yes? I have to admit, I made that mistake when I first started doing yoga (that and I started from a DVD, not a teacher). I was doing fabulously and slowly getting more flexible and strong, so I decided to add more before I was ready and instead of listening to my body when it was telling me it was too much strain, I continued to do the new stuff for a few more days and strained my back and then had to stop doing yoga at all for over a week. I have learned now to let myself gently and slowly progress.

So, I think the article had a few good points after shifting through the sensationalist phrasing. I know a critical reader will come away with the good points but I worry about people who don't read critically coming away with a false impression of yoga.
