Thank you for the mention at Beeber,

""What are the three most essential things you are looking for in a post and what do you think motivates you most to make a comment on an article you have just read?"

These are the three most essential things I looks forward to in a post;

Engaging content; if a post is engaging, I will definitely leave one or two comment on it to share my thought on the post.

I mostly look forward to a Quality post; the overall quality of a post will make me stay a bit to drop a comment, provided I'm not too very busy at the time.

lastly; Interesting: depending on how a post is interesting to me will make me want to wait and engage with the Author and support him or her all the ways I can.

I'm inviting @samsmith1971 to can and share her thought with us and keep this Lightning going.
