Well, it is a matter of fact that engagement always happens when the author is really keen to reply and to upvote (even a little amount to the commentators). People are here to learn and to earn quite logical point.
This is so true that you are quite senior member of this platform and obviously we the minnows expect favor in the form f an upvote from your side. It is matter of common observation those authors who communicate regularly with the folks gets a huge traffic on their comment section. I am fully agreed on the point that you try your level best to upvote on every reasonable comment and minnows like me should also understand the situation of the author sometimes.

I am always a huge fan of your contribution to the platform that is why i am your follower and i will remain forever.

More power to you @kevinwong <3
