Open Loop Keychain

Whackadoodles trying to parallel park while talking on a cell phone. Newlyweds bringing their infant to the 10 PM showing of Planet of The Vixen Stewardess Massacre. Amateur stockbrokers attempting a hostiile takeoover of MegaCorp at a drive-thru ATM while 20 cars line up behind them. Medicare recepients protesting government involvement in health care. What do they have in common? That's right: no feedback. They are everywhere. And they need warning labels. That 1/K investment return really is the thin blue line that separates civilization from chaos.
