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

I’m not sure you’re aware of quite how many things get “backed into CPMs” at larger publishers/advertising companies… for a Denton specific example, check out this craziness:

it makes sense to me that as Boing Boing would be very familiar with the publisher side of “CPM” as used in display. Certainly Abramson could have given a better introduction to CPMs. But this doesn’t read as a gaffe like you say. The other criticisms of the book are much more potent. My two cents as someone who works with revenue at a media company.
