Exactly. There is no reason to turn Hive into just another PoS shitcoin with no reward pool.
Contrary to what @therealwolf or some others may think, Hive (and Steem) have done spectacularly well from a monetary point of view. Pray tell, what other platform that has about 10,000 accounts transacting per day is worth 50 million dollars? For Hive (or Steem) to be in the top 20, we should have a market cap roughly an order of magnitude larger. Not going to happen unless our user base grows significantly.
How to grow our use base? Improved content discovery would be great. Content discovery is a front end issue. Let front ends deal with it. Any developer can fork the Steemit code base - or develop one from scratch - and tailor content discovery to any audience they wish.
Where I disagree with you is the need to store votes and posts on chain. That's absolutely crucial. Storing them centrally would completely undermine Hive's value proposition which is censorship resistance.
