hm ... I don't have trouble remembering things in books I've read ... but that reminds me, why do we read the New York Times if it's filled with forgettable, inane rubbish? :) Seriously though, I rarely remember the jibber jabber I've read in rags.
I think for most people, reading newspapers and articles in general falls into the glancing/skimming type of reading. It's not surprising to not remember something in that case.
