Value of article comments for understanding, information, education, development of thesis

Recently I wrote on two topics that are controversial to some. What I learned once again is the education I get, and others can, from reader comments. Those comments, directed to the article thesis itself, can expand the knowledge of the writer and those participating. I am always impressed with the level of sophistication on a topic expanded by readers who know specifics of a thesis the writer may not know or have time and space to develop.
