It is true what you say to analyze a tide of comments such as "Congratulations", "Great", "Excellent", or those who simply put an emoji I don't think it serves to value the content of the post.
I don't understand your question but I generally ignore single word comments such as you mention as the rubbish they really are.
That was my opinion precisely. It was not a question. I simply wanted to highlight the value of informed comments.
Ah ok, my apology for misunderstanding.
Comments should be relevant, valid and only be made after the post has actually been read. Single word comments are wasted. It's best to comment in such a way that the other person can engage a little and those single word comments don't do that.
