Clark is in Milwaukee again today doing listener-appreciation events with 10-year affiliate WTMJ. He's been thinking about the answer he gave to an entrepreneur looking to raise more money for his business. He picked up The Wall Street Journal and wished he'd told the entrepreneur about peer-to-peer lending, which was being featured in a story. P2P lending allows you to give banks the heave-ho when it comes to borrowing. Individuals who are willing to take the risk lend their money to others -- after carefully vetting a potential borrower's credit standing. It's almost like an auction, where people advertise how much interest they're willing to pay.

You as a lender have the opportunity, with risk, to earn a great deal more on your money than at the bank or a credit union. You can minimize the risk of default by splitting your money into a number of smaller loans. When Clark first heard about the P2P business model, he mistakenly thought there would be a high rate of default among borrowers. The Wall Street Journal reports such risk-based lending totals $100 million, which isn't much yet. But estimates suggest we'll hit $1 billion in the next 2 years. The Internet has given us the power to take advantage of this cooperative lending model.

Prosper.com is probably the largest and oldest of the P2P sites. Others include LendingClub.com; Zopa.com (the only one insured by the National Credit Union Administration); GlobeFunder.com; and Virgin MoneyUS.com, among others. People have become obsessed with this idea and there are already blogs and message boards dedicated to P2P lending. One caveat: Know your risk. There will always be people trying to clean up a mess in life with money. Know that sometimes you'll lose and sometimes you'll win with these sites. Rest assured they use collection agencies to go after those who don't pay.
