I haven't complained about a lack of good content. In fact, I have observed many great content creators see a tenfold increase in their rewards. For example, @boddhisattva has started to get rewards worth several dollars or sometimes even more than $10 in rewards for his photography posts. To my joy, the rewards of @digitalis have jumped from tens of cents to dollars, often at or close to $10. Both are pretty good photographers, @digitalis in particular, whose insect macros should've been rewarded at a much higher level than they were prior to #newsteem. Then there's the illustrious @paulmp, a very skillful professional landscape photographer who used to make a couple of dollars per post before HF21 and who now regularly makes double digit bucks. His most highly rewarded post made something like $60. At last, PoB is working!

I don't believe you, at least not without any kind of proof, that there has been an exodus of quality content creators post HF21 and because of HF21. What I've seen is many shitposters who have stopped posting altogether because their pending rewards got rightfully downvoted to oblivion.
