Not trying to be snarky, but you answered your question. Yes, some of the content posted here is worth money -- even if it's 0.1%. I'm surprised the authors post it here when it would be much easier to monetize a site they control -- without donating their efforts to a blockchain.
Then again, how many sites do you follow where you would pay for content? Maybe 0.1%?
So maybe Steem is average. Not great. Just average.
