There is nothing in his post to assume humor either way, "overt signpost" or not. This is written text, where you don't have the signposts that vocal communication allows, such as sarcasm. I don't insist on "overt signposts" but I'm not going to pretend that there was anything in the post to make the author's point clear. So here I am relying on my wit, experience, and judgement and I have no way to resolve either way. So I'm going to assume the author is trying to make a serious comment.
