last but not least, never comment on an article if you have not read it. So, you can lose your reputation in the eyes of the author.
I think this is the root to poor commenting, many people don't take out time to read and understand a post, they just go on with a general, "nice work", "interesting" etc, all this can be pretty annoying, to worsen it, some just drop links on your comments, I have had such situation, I wrote a post and someone just come and dropped a link to one of his post, it's pretty annoying. Anyways thanks for sharing this, I hope it gets to a lot of people especially we the minnows as we are often times the people who comment poorly.
Thanks for the Great Comment. I took into account all the sensible comments and added them in the second part of the article.
