Microloans for entrepreneurs in developing countries, loans that change lives

One of many interesting details is that women get the majority of the loans because they're usually far better credit risks.
There is no feminist agenda. Grameen lands mostly to women based on their own experience showing that: 1) Women are more likely to pay the loan back; and 2) Women tend to invest the loan in long-term basis (ex: buying a cow to sell milk). The fact is that women are highly marginalized in developing countries, and men magically starts to listen to them when they somehow are able to make decisions without the men's approval. Women have a vested interest in the loan, and therefore they tend to be better payers.
Don't believe on such "experts" -- If their theories were right, developing countries would be prosper by now :)
That's not particularly impressive from a financial standpoint, but it's certainly not a charity. It's more than most Web 2.0 startups make, after all.
Mifos is an open-source microcredit banking system, and they need volunteers: http://www.grameenfoundation.org/what_we_do/technology_programs/mifos_initiative/
Here's a good one. http://www.kiva.org/app.php?page=businesses&action=about&id=408
This is not theory: Millions of loans were granted worldwide, and in fact the default rate is actually lower than traditional banks in developed countries.
Note: My comments above are about microcredit in general, and not specifically about Kiva (which I don't know much about it)
