TRUST ON THE INTERNET: A website called Task Rabbit now allows people to advertise for things like: someone to come to my house and mop the floor. Or buy my groceries and deliver them. Sounds creepy. Why would I trust a stranger found on the internet? Yet, the free market came up with solutions: It harnessed the power of reputation, and now there are ways to know who to trust on the internet. PRIVATIZE IT: Margaret Thatcher was right. We should trust private companies far more than government: "The right honourable gentleman takes his customary swipe at private enterprise, he can't stand it. He'd rather have nationalization run by politicians who know nothing." MEDICAL ADVICE FROM STRANGERS: A new company called "CrowdMed" advertises: have your medical problems solved... by the crowd.

STOSSEL'S TAKE: Trust the market, and now -- the reciprocal ratings on the internet.
