Give me the short version! Recently I've been curious about books I should have read but never got around to, like "The Catcher in the Rye" and "Atlas Shrugged". There are lots of great books, "classics", that I'd really like to pick up some day but that aren't at the top of my list of things to do at the moment.
Are you in the same position? Then do what I do and go read book summaries on Wikipedia! The fastest way to find them is simply to go to Google and search for, e.g., "wikipedia the mythical man month". Most popular books have substantial summaries and analysis, so you can get the gist of a book without taking the time to read it. You'll be able to discuss the books at least as well as someone who read them back in high school, so you'll sound smart despite your laziness!
