Right now, its based on a mixture of posts that I have seen, recommendations from others, and a user having qualifying as a "minnow" account. I have only informally qualified that as having earned around less than 1M vests, but if anyone has a better arbitrary mark of what makes a minnow, I would be all ears.
I personally like to look for users that are helping the community in some form or another with their thoughts they share and actions in commenting or helping out others. Generally reading all of these users has made me better in some way, or affirmed the time I took to read them was time well spent.
Thanks for the answer @team-leibniz. I will definitely try to post Quality content.
