I don't believe this "ex-quant" in the slightest. He's OK on the technical details, but then right at the end, he doesn't make the connection. So, there's no cigar smoking arbitrageur doing the financialization of on-line advertising?

But as a consumer with "AdBlockPlus" turned on, I have to just say, "Rave on, Brother".
