Right, that's the point. This is a common style in economic blogs. They often follow the form: assuming some set of data, what are the economic implications?
> He does describe interesting models/theories, but I don't actually think they're relevant.
Right, they may or may not be relevant to this specific case (Reader), but I still found it interesting to learn about.
> It seems cheap and link-baity.
Hmmm, here we have a distinguished economist, who could no doubt live easily from his university job, instead spends time trying to bring scientific economic analysis to popular topics. Not sure how that is cheap and link-baity.
He does have a knack for catchy titles, though. If you aren't familiar with his blog style, "evil google" probably sounds bad (and emotionally charged), but I really doubt it was meant to be taken literally.
