Oftentimes there is institutional support for specific "mainstream" conditions (e.g. HIV, TB, etc.) and as a result, some patients who are in unique situations (e.g. have a rare condition, need a slightly expensive treatment, need referral care, etc.) often fall through the cracks. Watsi provides an opportunity to those patients by enabling them to tap into the crowd.
While there are pros and cons to each approach, it's important to note that they are complementary. Charitable giving is not a zero sum game, and we're working hard to expand the pie, not take a piece of it.
While you'd obviously always prefer to expand the pie rather than just take a piece, there's nothing wrong with the latter - like you said, your approach can help people who slip through the gaps, so even if the pie doesn't expand, your taking a piece of it can still be a good thing.
Keep up the good work.
Donors that are interested in maximizing impact, and not necessarily interested in helping a specific person, can give to that fund. We'll then use those donations to support organizational projects (e.g. $1 vaccinations and the like).
We're considering leveraging an organization like GiveWell to help us identify organizations and projects that will be beneficiaries of the general fund.
When I say not a fan of the concept, I absolutely don't mean I disapprove. I don't have any problem with organisations raising money this way, nor with people choosing to donate money this way - I simply don't like donating myself.
Trying to chose between fighting HIV or starvation, cancer or... etc. etc. is hard enough. Looking at Watsi's homepage, does Chimwemwe from Malawi deserve my money more than Kirshan from Nepal? What about Lidiya from Malawi? I can see the point of view that it's nice to know your money has definitely made an impact on somebody's life, but personally I don't enjoy the burden of making that decision. I'd far rather be 0.0000000001% of a big solution than 100% of a small one when it comes to charitable donations.
All that said, the fact that I dislike it doesn't take anything away from my thinking that Watsi looks like a great site, my opinion doesn't change the fact that anyone raising money for good causes is great and if the method used here helps that then no complaints from me.
