I would love to see MetaDAO lean more into gamified systems design. VC investors spend so much time and energy doing due diligence that when an investment gets approved, the majority of stakeholders involved have already convinced themselves to be long-term bullish.
MetaDAO ICOs are different in that i) the time horizon for payouts is generally much shorter, and ii) there is an expectation that the majority of DD has already been completed, with the result being "bullish."
Extending the time horizon for payouts would prob do more harm than good short-term, and generally speaking, you don't want to add additional friction or create a worse UX when trying to scale a product unless the goal is to increase monetization of existing users.
However, there is little to no downside in incentivizing stakeholders to do better DD. Adding a gamified points system that rewards users as they engage deeper with projects would shift user behavior for the better, create more robust user profiles for better targeting in the future, and embed a feature set that can later be leveraged to help projects with things like distribution and UGC.
