The problem with all the mistakes in Jill Abramson's book on journalism is you'll never know who wrote them

If anything, I’m struck that the article you linked could well be what “Abramson” read (and misunderstood) to create the paragraph in question, as the article refers to CPM and uses a novel derivative of the “Cost Per n” metric to analyze the traffic rubrics then in play at Gawker.

Let’s compare Denton’s Ratio to the numbers generated by another money-for-audience scheme in use on the Internet: online advertising. After all, lots of ads are sold using roughly the same language Denton uses: the M in CPM stands for thousand. Except it’s cost per thousand impressions (a.k.a. pageviews), not cost per thousand new visitors , which would be much more valuable. What Denton’s talking about is more like CPC — cost per click , which sells at a much higher rate. (Those new visitors aren’t just looking at an ad for a story; they’re actually reading it, or at least on the web page.) Except it’s even more valuable than that, since there’s no guarantee that the person clicking a CPC ad is actually a “new” visitor. Let’s call what Denton’s talking about CPMNV: cost per thousand new visitors.
