A point of view that differs from mine ? Great !!! Thank you for bring another perspective to the conversation .

My main interest is not Steemit; my interest is in people.

I would agree on that.

Here is where I differ from you and many of the other good members - If the poster does not touch me and I see no effort made, I shut their post with either no comment, or a rather curt one, telling them what they are doing wrong and warning them that there are those who love flagging such posts.

Many posters do that ( including me ) , but probably less often than others.

So, a question. Do you find it right for a poster to keep asking, in his or her every post to the visitor to upvote and to follow and resteem? Should such reactions not be from the visitor, because he/she/ finds your post exciting/worthy/interesting/funny or whatever?

That is an interesting question. These gifs you see are called Call To Action (CTA) and it is the action we want the reader to take after he/she finishes the article. Conventional blogging wishdom that cames from research says that if you don't tell the other person what do to, it is possible that it will do nothing.
If you have any research that says any different I will take it into consideration.

And last about the asked "I love you". Some people brains are hard-wired in a way that it is important to them to be reassured of the love of the other person or they need to listen to it. Don't be harsh them , it's their neurology that's speaking. :)
