Quality is also hard to quantify. I have seen posts in my niche diving who wouldn't make it past an editor but who are interesting for me.
I think adding communities where you have like minded readers would also help but off course this is easier to establish in a small niche like diving then in the big communities like travel where you need a higher level of quality to jump out.
That's true!
At some point, quality is subjective. Sure, there are obvious shitposts, but I've seen great articles presenting great concepts once I get past the punctuation and grammar from people who are writing English as a second language.
