Wholly crap you are right, maybe btc would allow kiva to bypass the field partners altogether and offer 0% interest rates.
That would be pretty cool.
I didn't know about Kiva either until someone told me a few months ago, I was gonna donate until then. And yeah, that would be cool. Depends on whether or not they actually do any lending, looks like they are just a middleman doing the pr and organizing, outsourcing the actual lending to subcontractors. At least a couple have decent rates, but a lot are 30%+, with one as high as 62%. Maybe the person who posted that thread can chime in on how they operate.
A lot of good options there too, maybe start with the smaller ones. It'll be easier to convince them if you are talking to the guy who can actually make decisions.
