You wrote a beautiful post and I completely agree with you.
I always try to comment and interact with as many users as possible, time and work permitting, because it is by interacting and comparing different ideas that we grow and improve.Hi @elcomentador :)
When I comment several times an author and I never receive answers I end up not following and reading the author because as you said, not responding to comments is a sign of little education and little humility.
Obviously there are logical exceptions such as those who receive a lot of comments and only in that case it is justified not to respond ...
Really nice your post because it stresses the importance of interaction.
Hive a nice day :)
