As one of Giraph devs I really like the idea of having TinkerPop in ASF. A few questions/points: * could you please post the proposal to: https://wiki.apache.org/incubator/TinkerPop Proposal (let me know your wiki ID if you don't have enough karma) * do you guys have a champion and initial set of mentors in mind? * could you please fill out affiliations section?
