That could be Ingvar, Im not sure we can offer any hard evidence of your point or mine, but I will concede to your point; however, I do agree that Kiva enthusiasts are more likely to loan short term, under 12 months, as opposed to long term, over 12 months.
For myself, being new to lending, at first I also didn't look at loan terms and just went for the connections. Then I realized that I didn't want to wait that long to re-lend, so I searched for a few shorter term loans.
Now that I have loaned as much as I can safely have out there, and will need to rely on re-lending for my fix, I at least only have a few months to wait.
However, I am going to strive to keep as balanced a portfolio as possible, including loan terms. A few long term loans in my portfolio will make for a nice balance, even if I don't get my lending fix as often on that portion of my Kiva fund.
Just my 10 cents...
