Arnold Snyder wrote an excellent post about talkative players at the poker table a while back, entitled
Shut the Fuck Up. Some poker players just don't realize that educating the fish makes the game harder.
People's propensity to talk too much exists in all forms of advantage play and investing. A fine delicate line exists between sharing ideas among private individuals and shutting down the game.
A couple of years back one could have taken simple algebra and made a lot of money gambling online through the various bonuses. The returns on some of these games were equivalent to a ROI of 100% for about 10 minutes worth of work. No kidding. That was precisely how I built my small fortune with a couple of hundred dollars.
The first popular site to discuss these ideas decided to shut down its message board because of the information leaks. Another site popped up to replace it. The leaks weren't as bad as the previous site, but that site shut down too. The current most popular site has a new owner that does not understand the value of silence. Any and all ideas are discussed and talkative bitches have killed the game. Where ROIs of about 30% were common, now the most common ROIs are about 1%. The game is dead after factoring in the risk of having one's funds stolen.
What most people don't realize is that excess returns are proportional to the flow of information. A broad interdisciplinary understanding between information theory as it relates to gambling, investing, and maximization of wealth would clearly illustrate this. If you care to explore this idea further I'd recommend the book
Fortunes Formula by William Poundstone.
By writing this very post I am also guilty of contributing to the information leak. I'd like to believe that my contribution is much more minimal. I don't mention too many specifics and have not discussed the strategies or the ideas behind these opportunities, but the very act of mentioning them is a leak. I maintain this blog so that I can crystallize my thoughts into a concrete form. The value from forcing me to organize my thoughts exceed the slight leak it might cause. I apologize for that. If at anytime I feel this site is hurting my profits, I'd shut it in a heartbeat.
Relating this to the investment world, people with high Investor Quotients (IQ) don't discuss their methods. Rather than proving to the world they're right and the Efficient Markets Hypothesis is wrong, they'd rather make millions and billions. If that much money is on the line, they know how to the STFU.
If you spot an investment opportunity, $100 lying on the floor, or a game that can be beaten, don't tell others. STFU and take the money. It sounds simple enough, but people can't keep their mouths closed in real life.
