This depends on how quickly we can engineer the right incentives and see them get adopted by the userbase. Short answer is, 'as soon as we can'. Right now we're still unknown and trying to bootstrap initial engagement. But the faster we can get Reviewers earning meaningful sats from other users, the faster they'll see the ROI, and be willing to write reviews for smaller and smaller (and eventually zero, and then negative!) upfront amounts.

I've spoken about content in another answer in the thread, but we want to be careful with it. It's not clear for example what value a review has for podcasts - do people want to see individual episodes reviewed, or an entire show?
