This is my reply to
Ronan's suggestion to have Kiva's main revenue stream come from advertising on the site.
In a nutshell, Ronan suggested Kiva model its site after Facebook or LinkedIn to generate revenue from advertising, and then listed a number of benefits to that approach. First off, I'll say Kiva generating some form of revenue stream from Internet advertising is a
great concept!

Of course, exactly how that might get implemented is the rub.
When I read Ronan's suggestion, another style of nonprofit/for profit arrangement came to mind - the
Wikimedia Foundation,
Wikipedia and
Wikia. Essentially all the brainchild of one brain, these three organizations weave a tangled web, but simplistically and loosely can be thought of for this suggestion as an overarching parent foundation, a nonprofit arm and a for profit arm.
When I went to a Wikia site I've highlighted
elsewhere to find an example of the style of advertising they use, this is what I found!

Now, I'm
not saying Kiva should get MicroPlace as an advertiser, but hey, don't some interesting possibilities come to mind?!

To get a little closer back to the point, here's an approach that seems to have some long-term potential to me. The parent organization, Kiva Microfunds, runs the show and operates the nonprofit, zero interest and advertising-free "Kiva.org". It develops another spin-off or simply uses the one it already has for managing its overnight float account to operate "KivaToo.com"! KivaToo accepts advertising and regularly sends checks back home to help support the more asthetically-minded family members.
And this for-profit sibling looks into the possibility of setting up some sort of broker/dealer arrangement with selected partners to offer modest levels of income to lenders, while
still offering below market rates for loans to its partners. One way to help offset other costs to these partners might be to eliminate journal requirements and simplify listings.
