Hi HN! Excited to show off the project we've been working on for the last couple months. We started with an idea for a crazy twist on prediction markets: You come up with a question for traders to predict, and then decide the outcome yourself.

Curious to hear feedback from the HN crowd on features/dynamics you’d like to see added.
