i've never met zed, but am always impressed with his honesty in everything i've read written by him. I don't think one can ever say that he doesn't actually believe what he claims.
Don't you find him to be a bit narcissistic? In any case, I usually read his writing, but I've found his tendency towards autobiography and self-promotion alarming at times.
Probably. Bottom line is that we can't judge an individual based on something as trivial as a blog, but quite a few people seem to take blogs and such very seriously.
