I think I have succeeded in fixing the comments problem that a user pointed out. Please let me know if I have not fixed it.
While it would be pretentious to claim that this blog has a "comments policy," I can say this much: discussion is welcome, more often than not comments will get replies, and I delete comments very rarely, only if they are really useless or if the comments section is being used to insult or abuse people (which I do not equate with criticism or disagreement). Whether it is due to luck or some of other factor, this has only happened a couple of times. And while you certainly can comment anonymously, I have greater respect for people who do not.
