I've heard good things about this from a couple of people now. It appears to combine cult-like (used non-perjoratively) marketing techniques with potentially valuable self-examination. I think it is quite expensive though.
As for why the public confessional: support groups like Alcoholics Anonymous use this kind of structure don't they? "Hello, my name's' El Salsero Gringo, and I'm a compulsive Forum poster."
