I never met Dan John , however Im very familar with his literature.He was the one , who introduced me to T-Nation. What I really liked about Dan ,was that he was there ( im talking about his site) to educate anyone that was willing to listen.And basicly he was doing it for free!His e book is free! He may make a few bucks from his lectures ,but I sure its worth while.
Some of the other authors are trying to make a buck ,which is fine.Their goal is simple , sell product.Some good ,some bad. Some new ,some have been around for a long time.
Dan wants you to make progress.When I read material from his site , I feel he wants to share his knowledge .Other sites are basicly a marketting tool. If you buy the book ,you must buy the video and then buy the ab machine-thing.
One day I d love the chance to meet him
