For some reason I couldn't reply to your comment initially, so I put this in a sibling (typos and grammar excepted):

I haven't touched any of my comments since they first received a reply. I often touch my comments within a couple minutes of posting in order to correct typos or clarify my intentions, usually by appending a paragraph. But I don't do so without remark once they've become canonical in a thread.

Your replies to my comments are as they were written.
