Seems like you haven't read much of Dan's blog as he specifically says that he does little of research into specific names and instead fills out his portfolio with a wide net of situations he thinks are attractive in totallity. Sounds like you uncovered an interesting tidbit regarding addresses but chose to gripe about it here instead of informing his readers and him.
I think bloggers create more value when they introduce their readers to names they haven't heard of before than when they offer a new perspective on a known name. Then I can at least start tracking them even if the valuation isn't compelling to me at the time.
