Great advice. The bots are nice for earnings but bad for ego for newbies. When I first started posting, the bots annoyed me. I thought they were all abusive. I've come to sort of ferret that out now.
But genuine content producers want to know that their post was read. A comment (like the shading example you use) shows the author you took time to read. It is not even so much a matter of respect for me as it is acknowledgment of the content. I would rather have a disagreement on a point than a bland post.
Thanks for sharing. Hopefully your points will be embraced by more people here.
