I do not think this can help solve PoB. 50/50 curation and a separate downvote pool might.
Also, we should maybe add some centralization on steem, demanding from bidbots to burn 10-20% or the steem they earn. This will still allow investors to earn a good return while helping the price of steem.
Eyeballs will help the steem price raise. Advertising through bidbots is an amazing sink for the coin.
