There are some people, some sources that are established authorities on certain subjects — in some cases, quite broad categories. For example, Consumer Reports is widely considered authoritative on all sorts of consumer goods purchases, and William Safire is generally thought of as quite the grammarian and lexicographer.
Yet, when I’ve found myself in the position of reading Consumer Reports reviews of some product category that I’m knowledgeable about, I find that they’re generally bogus to some extent or another — and, recently, when Safire addressed “Blargon”, he got major points wrong and completely misrepresented others — I seem to recall Brad coining ‘blogosphere’, for example, not that other guy, and being completely tongue-in-cheek about it.
The other aspect of this is that if Safire is talking about weblogs, we’re at the point where the carcass is being dug up and tossed over the shark — so where’s the next thing?
