Great advice, and great fun... I'll buy that for a penny ;)
I can usually tell a good commenter as well. Maybe we need to recognize those more often. The good ones usually keep commenting as they continue to read all of the comments attached to a post.
In fact, that's where I usually find the greatest thrills when posting on Steemit!
Exactly, there is a real conversation happening on a good, engaging post. Become part of the conversation if you have something insightful or meaningful to add.
Sometimes I will read all the comments on a post with a topic I know nothing about. I'll just be a fly on the wall and say nothing, just learning more about the topic. You can learn a lot on Steemit. Some of the best stuff is in the comments.
