You meant to say "keep in mind A reason" not "the" reason.
Some, myself included, would simply say AVENUE Q is a better musical than WICKED.
There's a whole lot of speculation about a whole lot of voter strategizing in this thread. In my experience, it is never as cohesive an explanation as it seems. Some voters indeed behaved precisely as speculated here, some voters didn't. This is why you'll find exceptions to each pattern. Some years the critical darling wins, some years it loses. I wouldn't have agreed with each choice, but I haven't been surprised by any.
Words don't deserve that kind of malarkey. They're innocent, neutral, precise, standing for this, describing that, meaning the other, so if you look after them you can build bridges across incomprehension and chaos. But when they get their corners knocked off, they're no good anymore…I don't think writers are sacred, but words are. They deserve respect. If you get the right ones in the right order, you can nudge the world a little.
