Yep. Actually a couple of times.
My first comment was a detailed criticism of his rant, noting that (1) registering multiple users and upvoting your own content is gaming the system, (2) when pg criticized him for it he said "I got you" but clearly didn't "get" what pg was getting at, (3) his failure to link to the original on twitpic was a violation of HN's submission guidelines and pg was actually cutting him slack by requesting that he include a link instead of changing the HN submission, and (4) HN's guidelines explicitly state that editors may change your title if you editorialize it. I noted that for someone so stuck on pg not giving him guidelines, he was awfully ignorant of those guidelines.
They stripped all of that out of my post, leaving only a poorly edited variant of my conclusion.
I added an addendum about how "egotistical, pompous, and self-serving" it was to spam this to HN, which he edited to say something libelous about PG.
I sent a note saying how classy that edit was, which was edited to use a different username (!) and was totally incoherent.
Quite impressive, really.
