I also had the initial reaction of being a bit put off by Carter's approach, which is why I specifically asked him what he would say to people who are put off, or are naysayers to this approach. It does seem self-serving, on the surface. However, the beauty of actually talking with +Carter Gibson
and virtually interviewing him was that it became clear that Carter's motives are far from self-serving. They are actually about raising awareness, raising money, and creating activists.
The biggest challenge with Google+ fundraising is that nonprofits are not yet allowed to put up Google+ identities (Google is taking down these profiles as quickly as NGOs put them up). The challenge with fundraisers like Carter's is to iterate them so that they don't appear to be even a little self-serving. If the Red Cross had a Google+ profile, then Carter could say "I will donate $0.50 for every new person that puts the Red Cross in their circle." There may also be other iterations on the peer-to-peer fundraising model here, and I'd love to find out more about others doing it.
