"The Shallows: What the Internet Is Doing to Our Brains" by Nicholas Carr. I'm halfway through it. The main thesis of the book is that the Internet has quickly modified our brain (neuro-plasticity) so that we absorb information quickly but we don't get deep into any topic any longer.

The book start strong with this thesis and then goes into a very interesting detour on the history of writing, from the egyptian to Gutemberg all the way to Vint Cerf.

Very well researched book and well written.
