Technopoly was floating around my fraternity's library. I picked it up randomly, and loved it. Postman didn't write the ancient Egyptian myth told in the beginning of the book, but Pharaoh being cognizant of the downside to Thoth's gift of writing to mankind was eye-opening. The rest of the book was also good. It really changed my prospective on technology, to always be on a lookout for hidden downsides to seemingly universally beneficial technologies like writing.

(MIT fraternities may be a bit different from what you'd expect. About half of MIT undergraduate men are members of fraternities.)
