What if you needed to borrow a couple thousand bucks to replace your washer and dryer but didn't want to pay 18 percent interest on a credit card?

What if you had a couple thousand bucks but wanted to earn more than the 2 percent on your money that you would on a passbook savings account at a bank?

Such is the idea behind Prosper.com, a Web site designed to anonymously link borrowers and lenders in the spirit of eBay.

Of course, the best idea is not to borrow money at all (see also: financial guru Dave Ramsey), but if you have to, this is one interesting concept.

Prosper was founded by Chris Larsen, the founder of E-Loan, an online mortgage broker. Once he shook up that market he decided to shake up another.

What's in it for the borrower?

Generally you will pay a lower interest rate than on a credit card, a bank loan and (shudder) a payday loan joint. You specify your own repayment terms, the interest you are willing to pay and lenders bid on your business. You can borrow up to $25,000 for up to three years. And you have to release your income and your credit score. (A credit rating and a debt ratio is released to your potential borrowers.)

You also can join a "group" of like-minded borrowers that may make you a more attractive risk.

What's in it for the lenders?

Here it gets a little more dicey.

If your borrower pays as promised you can get a decent rate of return in many cases (certainly a lot better than a bank savings account or a CD).

There is one main strategy that lenders use to reduce their risk: to widely diversify and invest across lots of individual loans to reduce your individual exposure.

It's a tad hard to explain, but it is explained well on the site. I am not necessarily recommending the site, but it is another sign of how the Internet is changing how things are getting done.

When my mother passed away in 2003, I found a Web site called "Beanies for Baghdad" to which I donated her collection of Beanie Babies. They are now in the hands of Iraqi children thanks to American troops, which distributed her toys and tens of thousands of others. See www.beaniesforbaghdad.com.

Without the Internet how could such a worldwide grass-roots effort have ever existed?
