This is a great idea, as it is a 'meta' idea, in that it is about making the new ideas faster and better. However, I think that what is proposed is a moderation issue. GAIs seem to be a bit of a ways off still, so humans are still the ones that need to write these messages and determine what would be prompted to be shown. As such, I think that a (gasp) market economy may be a good way to get people to do this. Maybe you can get an 'expert' to be paid to write these messages and as payment, they get some percentage of "ModCoins" that are mined in the background. I know that's not very much, right now, but who knows.
