Thanks for the correction. I typed the previous comment on my mobile, and the autocomplete there is quite confident with apostrophe insertion, which I don't always notice and correct.

You are incorrect though regarding Skitt's Law - this sequence of posts is not an example of it. My comment is mainly about the subject under discussion, with a post script correction on a tricky spelling error. Your comment, which is purely a correction of a common spelling mistake, contains no errors so far as I can tell. Thus, you are the spelling pedant in this situation (even implying I should be embarrassed for making a spelling mistake) and yet, you have no spelling errors - exactly disproving Skitt's Law.
