This article is geared towards reading more books like its a race. It would seem better to reread a few books to really grasp them. I think there is something to be said for rereading versus reading more new books.

How many times were we discussing something we read and all we can really say is "I read a book on it. something to do about blah blah. I forget the details." No real insight or grasping of the material in one read.

Maybe a book club that focuses more on grasping fewer books very intimately over constantly reading new ones. Just a thought.
