I like this. I think it’s worth a crack. Getting the community to vote on rewards mechanics seems the correct direction.
I’d shorten the initial period, not because I don’t think 6 months isn’t correct (I think that or quarterly is the right cadence) but because you’d want to get one full iteration out quicker to validate the idea.
You want to throw out some some ideas around rewards conditions as a test in another proposal? I think we need to validate that we can actually come up with a set of reward conditions as a community, even if they’re ultimately not going to be adopted there and then.
