Try to solve the same sort of problems Arbital or Metaculus is optimizing for. No reason to step on the toes of other projects in the community.
I don’t think that it’s bad to have multiple website that gather predictions. It’s good to have different websites trying different approaches.
Metaculus has curated questions. Users can suggest new questions but they have to get chosen. Predictionbook allows user suggested questions. GJOpen is completly curated without much ways of users to suggest question (expect a bit, see the recent question for new questions)
Metaculus starts by showing the user the average guesses of the community before the user votes.
Metaculus let’s the user pick probabilities with a sliding scale. Predictionbook lets the user input a number.
GJOpen let’s the user click two times (you click first on 10-19 and then on 14).

All three try to score users differently.
I would welcome more experimentation.
