Interesting question. I read her post, checked out the blog, disabled Adblock but still didn't see any ads. So I disabled Ghostery as well and finally saw the source of her income. My initial thought was "who the hell clicks these ads?". I suppose the target group isn't people like me who use extensions Adblock and Ghostery. And people like me are (and probably most of you) - at least for now - a pretty small group among web users.
