Hello [lucyanna], thanks for joining this project.
Vilfredo is a system that tries to explore the space of possible answers to an open question.
The system works through successive approximations. Each round is called a generation, and each generation is divided into a writing phase and a voting phase.
As such users are invited to propose answers (voting phase), vote each other answer (voting phase), and through some matemagic, a subset of the proposals that represent each and every body is presented to the next generation. Then the participants are asked to propose again trying to integrate, modify, correct, merge, the existing proposals.
Respect to your model, Vilfredo would be a tool the specialists to really explore the possibilities out there. I think it would work quite well with some traditional voting system that would let everybody evaluate the last set of proposals and make them available for vote.
Cheers,
Pietro
