What is quality content to you?

This is the million dollar question, ​to be honest.
In my own opinion, any piece of content that has a specific value to deliver.
As we all find value in a wide variety of things, it might be;

• A helpful information in a particular area - there's always an audience for it.

• Entertainment

• A provocative piece

• Enlightenment

• Inspiring others through our own journey.

• etc

It can really subjective.
