Thank you.

I suspect that I may have missed some point, though. As far as I know, the primary language on this website is English, and the secondary language would be the language of mathematics (if I may call it a language); and so I don’t quite grasp the relevance of being competent enough in any language but English to the matter in hand.

On a side note, I think that for many linguistic perfectionists the main source of intimidation would be the very process of writing a comment or article (as opposed to being aware of the likelihood of having committed a number of grammatical or semantic mistakes). It is true for me personally. In writing a text in any language but Russian—my native language—I don’t feel confident enough to proceed without consulting various corpora and dictionaries. Then I end up with a comment composed almost entirely of expressions which I saw in dictionary samples and liked better than my own expressions. This is a rather strange experience in its own. Besides, after spending a time on a simple comment, thoughts begin to race in my head that maybe, perhaps, it wouldn't really be something that the other people couldn't conclude or know on their own: “you know that I know that you know that I know et cetera ad infinitum”, this sort of thing; and so the amount of information would be exactly zero. Why increase the entropy? :-)
