If people recognize something as being worthy of mockery and they are also aware of the situation, they gain nothing from reading some tripe that provides zero new information.

Also, a blog post shouldn't assume that all readers have seen the interview in question. What's the value of talking nonsense about something the readers have never been informed about? At most, the rational readers would be disgusted by the attempt to influence their opinion before they'd seen the facts.

Well, the readers may not know that the mocked person doesn't know his own address, so when the author doesn't explain it, the author is the foolish one.

If the readers know the facts, mocking someone for trivialities without pointing out some novel reasons "why" is double foolish.
