This addresses a lot of complaints people have with ads from a UX perspective, but misses some of the technical reasons that a lot of folks (probably disproportionately represented on sites like SO) have for blocking ads and tracking scripts, which is that they're fucking intrusive, not just on a given experience but into one's life. Since most ad impressions are coupled with some persona creation and event linking these days, it's not as simple as "we want to make ads more relevant and high-quality".
