My loaning tends to be like optimistic.bob's, I like the smaller loans and I trust Kiva and their partners to do the business end. I never consider 'repayment'.
I am also trying to lend in every country (23 or 24 now I think?) and I try to get in on Honduran loans, expecially to Teguigalpa. I have an active (and even an official) interest in helping Honduras.
I have gone and bid on the oldest loan, just 'cause it was old.
And I have joined in challenges by the Pondering Pig group to help fund individuals.
And yah, I lent to a pub owner 'cause I like pubs!
As a vegetarian I sometimes have issues with cattle and such, but I do realize how much it helps them. But I don't think I will be lending to any gerbil farmers when those Mongolian loans start coming in...
(FYI a gerbil is like a mouse and it won't be farmed, I'm joking)
