The author asserts that "more ads, fewer users, lower revenue, more ads" is an unavoidable death spiral. In actuality, any property owner with a rudimentary awareness of the concept of diminishing returns will understand that there's an equilibrium point: too few ads and you're not monetizing to the fullest, too many and you annoy enough users to damage the property.

I like the concept of a service that tracks adblock usage. That's actually something that's missing: insert a tiny javascript tag that adds a Google Analytics counter for adblock usage.
