I looked and looked, and my first thought was "He doesn't like Schoolhouse Rock? Schoolhouse Rock isn't political."

Then I noticed this from the start of the article, "Like the small-town mayor who suddenly finds herself running an entire state, our ambitions for Stack Overflow keep growing."

I have a hard time finding that to be anything but a casual and not very detailed analogy. Sarah Palin -> lots of ambition::the SO team -> lots of ambition. How is it snarky? (If anything, he's comparing himself and his team to Palin, so how snarky could it be.)

You're overanalyzing, I think.
