Thank you for the feedback! I would say more humanist than Quaker, because there is no mention of the supernatural or deities. Although there is nothing to stop someone making an agreement containing the ten commandments, personally I wouldn’t sign that one myself.
It remains to be seen whether the proposed reputation system would stand up to abuse or devolve into noise. I’ve been house sitting for two years looking after people’s dogs and cats (trustedhousesittters.com) the whole system rests on trust and reputation and mostly works quite well, so there is prior art to reference. Also a lot of naysayers never thought Wikipedia would stand up to vandalism and yet the system has proved surprisingly resilient. I suspect the concept would appeal to the more ethical folk initially and gradually spread to the general population.
