I guess my problem is that based on the quality of his advice, Skip Williams doesn't deserve to be the primary authoritative source on the 'true meaning' of the PHB.
The job of the Sage is to clarify situations where the rules are ambiguous. He isn't going to be consulted in situations where the rules are clear-cut, because there's no need.
If the rules are ambiguous enough to start a war in the first place, then appealing to the Sage is hardly going to end it, because that's not how flamewars work. All that happens is that one party puts on their "Skip agrees with me therefore I'm right" hat, and the other party puts on their "Skip disagrees with me therefore he's wrong" hat. None of this is a reflection on Skip himself, but has to do with the nature of online discourse.
By and large, I think Skip does a pretty good job, and I think most people here would agree with me. And yes, I've put on my "Skip disagrees with me therefore he's wrong" hat a few times.
Re Feats - the PHB says that to get multiple attacks, whether iterative, off-hand, or from Feats, you need to take the Full Attack action. Disappointing to powergamers perhaps (When I'm playing I'd love to Cleave off a charge!) but hardly ambiguous.
Get off your high horse already. Just because you've put on your "Skip disagrees with me therefore he's wrong" hat doesn't mean the rules aren't ambiguous. It certainly doesn't make everyone else who disagrees with you a powergamer.
In fact, a feature of Sage Advice that more than a few people have noted is that if there's a choice between powering up an ability and nerfing it, then more than likely Skip will go for nerfing it. He seems to have an aversion to power inflation, something possibly resulting from 20+ years of watching the game evolve.
