Spot on mainly - a social media platform will never be a mainstream success on a blockchain at least not when a reward pool is involved. It is simply not working, so unlink the reward pool from the social media posting stuff that gets rewards for posting shit here. The blockchain will benefit from good Apps or DApps moving forward -focus on them and the prize might go into a better direction.
In general, I agree. However, before dismissing the reward pool entirely, maybe there's a better method of allocating rewards.
The real creators and builders of apps that make the blockchain a better place should be rewarded but no idea how this can be implemented and based on what (stakes / reps)? I still have some hope - are communities comign and will they help? Maybe allocate reward to comunnity leaders that have to apply / proof their capability?
