Steem already has far superior discoverability thanks to financial incentivisation of curation efforts.
Unfortunately that may even be counterproductive (regarding vote buying) because most people "curate" where they think there will be a lot of upvotes. So if you know user X will always buy a $10 vote, thats a sure place to place your vote.
I have found that it's much more profitable to vote on undiscovered posts, as there's no competition. A user that will always buy votes (or more important, is very popular, so guaranteed high payouts) - bots and humans alike will latch on to those. It'll start a bidding war where you'll often have to vote at 15 minutes or earlier. It's stressful and when I tried that it was never as profitable as just voting on exceptional but undiscovered posts.
If you want to get curation worth 10$ on undicovered posts, you need to put in at least one hour.
Voting on those guarantees only takes 10 seconds.
