The designation of "quality" is dependent upon the reviewer and their success. Take for instance the following topics and examples:

• Hive account@stemgeeks - Any stem topic
• Hive account@theinkwell - Short stories
• Hive account@splinterlands - Short stories at an entirely new level on Hive. I would buy their books if they actually sold them.
• leofinance - Financial cryptocurrency related topics

I've just listed a VERY small example of what I feel is quality content. Take splinterlands, for example, each story they produce has CEA: content (professionally written), engagement within their community and beyond, and activity. It seems like including these components in each of their content drives their platform forward.

Hey, Hive account@mineopoly and Hive account@samsmith1971, have you read some of splinterland's work? You know, the stories behind some of it's characters? I just found out about it and it's difficult to pull away from it to do other things. It draws me in almost as strongly as the stories in the gnostic gospels.

Anyway, enough about SPL? Back to quality. Creating it depends on your interest and natural fondness of the material, I think. Take your time. Make your posts based upon topics of your interest and see how things go. Tailor your work as you see fit to adjust to the needs of the community you're addressing. And watch your support grow.
