Jind: without looking at your links. While I agree with you, I'm a big fan of "self-help" books/ebooks (not so much DVDs). I've bought a bunch in the past years and I've yet to come across a single one where I was disappointed and ended up thinking "this wasn't worth the money". Then again, I'm of the opinion that every $ invested in education is a $ that's invested well - and I believe that I can come away with only 1 or 2 useful things from a $15 book, it was worth the purchase. Of course people who have less disposable income may disagree, but it's worked for me so far.
There's nothing bad about money and if someone who has "credentials" decides to make money by sharing experiences, that's fine and dandy for me.
