Hello @maryfavour
Thank you for this insight. I try to reward those who engage in comments too but sometimes get discouraged to do so since my upvote is not even up to a cent. Well, I guess this is a new motivation.
I know for sure that when some visit to read blog posts, they only do so to read comments. More so, many only go to the comment section and see how people are commenting and make their contributions based on those comments. I do that , sometimes, especially when I do not have the time to read a very long post.
It said humans have some attention span, I believe mine is shorter than most others. Most post on steemit are long and wordy. It will go a long way encouraging and advising people to write posts of few words that go straight to the point. Thus, enabling a true and worthwhile engagement.
Take care and STEEM on!
