He knows his stuff, and has a flare for writing, but I always want to say "but" when someone posts an article of his. The "but" is that he overcomplicates and makes it harder on the brain than it needs to be......when you simplify all of it, he's right, and I get the feeling overcomplicating makes for a better read because if he just told you what he needed to, most people would get bored half-way through......basically if you know enough to sift through that and unserstand the ''hows'' and ''whys'', you'll be fine.....if you think it's magic, you're better off with Ripptoe's 3x5 or the 5x5.
