I, too, will be/am sorry if Optimistic Bob quits Kiva Friends (for one thing, that name always makes me smile)...
However, part of me thinks that leaving Kiva Friends might help rebuild his love of Kiva! Here on Kiva Friends, we discuss every aspect of Kiva, of Kiva reporting, of ways to improve Kiva, of things we don't like about Kiva, IN DETAIL, sometimes way too much detail.
Lenders who have 20, or 50, or maybe even more, loans out, who DON'T read the Kiva Friends posts, are likely to be happy lenders. They made connections, payments (or refunds) usually arrive, defaults are still low... whatever reasons brought them to Kiva remain intact.
However, new (or even seasoned) readers of the Kiva Friends forums get an earful on every possible problem. I don't mean to say Kiva Friends aren't positive, or that we don't post lots of GOOD - but if I was not an active reader, I wouldn't know about or think about what happens to my loans if I die (which I still do not consider a problem), paid-back vs. refunded (yes, Henry, I agree that you are right), duplicate postings (which I consider a boo-boo, not a scam), etc. I LIKE reading about all these concerns, and seeing all the different points of view, but I think it can really warp a lender's perspective.
I became active on this forum as a way of staying AWAY from Kiva when I needed to restrain my lending frenzy for financial reasons. If I ever find myself losing interest in Kiva, I will stay off Kiva Friends for a couple weeks and see if my enthusiam bounces back.

Safe travels,
Laurie
