My thoughts are that they all depend on the trending tab staying incredibly basic. Look at all these developers working toward the same antiquated goal. Do we really want to delegate thousands of development hours into this sector?
What they should be working on is a better trending tab. Proof-of-brain incentive is what developers need to be working on achieving, and I don't see a single project on Steem even trying. Everyone seems to be a lot more worried about making sure they get paid instead of making the platform better as a whole.
