This entire thread can be summed up in one word: MONEY.
Jeff, Andrew, Ken are all...wait for it...greedy assholes.
They each have something to gain from the success of their respective websites/products/services etc. They want you to drink their Kool Aid and have spent the better part of their careers getting people to listen to them and buy their stuff. be it books, workshops, or whatever.
I guess you think the same about our host Michael who promotes his $15k trip to Antarctica on this website?
In fact... you could say it about any professional endeavour. People do stuff in order to get money so they can buy food and put a roof over their families' heads. It's not greedy. It's survival. IMHO the fact that someone has been able to make an income year after year doing something makes me trust that he or she might actually know something about it. I'm far more weary of fly-by-night websites, training courses, etc, which pops up, pretends to be the bees' knees, and then disappears after 12 months when the hobbyist running them decides to spend more time on his or her real job.
It's not being a greedy *****, it's being a realist!
