Fixing poor tone is definitely great, although I suggest if you edit, then make that clear, as otherwise you confuse people and people will silently assume you are acting in bad faith.

Note that I often downvote any mention of the word “downvote”: I am sure you asked in good faith, but as a sweeping generalisation, commenting on voting doesn’t improve conversation. Not knowing why you get downvotes is a “make you think” feature IMHO. I also believe excessively caring about votes is a red flag: some of the best commenters seem to be fairly neutral about caring what the HN voters think.

Not trying to start a conversation about voting and maybe my comment deserves downvotes. I am answering your implied question about why you might get a downvote even after your corrections to “tone”.
