While the post was in second person, it was addressing the reader. It's sort of like the umpire when he makes his calls. "SAFE" and "OUT" are merely for everyone's knowledge, meant for everyone to hear and his judgement are never exclusive to a single person, as an umpire that doesn't make clear his judgement would be a very, very bad umpire.
Stocking, what the forget? You clearly are not getting it. You implied that he used an interrobang, more or less. However, he did not. It is literally that simple. He either did, or he didn't. And I think it's pretty clear that he
did not use an interrobang in that post, or in any post.
