Yeah some do, some post great content. But there's a lot of garbage that's earning hundreds of dollars. I have no problem with someone posting garbage and getting a lot of money for it, good for them I say.
The only real problem is the zero-effort garbage is far too visible. People chasing curation reward always go where the money is. It would be nice if there was a way to incentivise curation by quality rather than dollars, but don't know how that could ever be possible.
Half these garbage posts have barely any views on them as well, so it's not like people are really interested in what some dude had for dinner.
