I meant a moderator in the context of moderated discussion, approved etc. Financial markets have a large skill requirement and a easy way to destroy yourself.

Alright what about a bet of 500-1.5k comparing risks that I have personally taken that inform my decisions say versus yours signed via openpgp key and how that informs our views. Done via escrow. I've seen people lose in a variety of contexts. People who have not taken risks make lame jokes like yours. People are providing stupid investment advice saying things that "sound good". Otherwise the blog Bayesian Investor should be sufficient.

More advanced mistakes.
