Freakonomics authors Steven D. Levitt and Stephen J. Dubner were guest bloggers for Google several days ago. I have not read Freakonomics yet, but plan to do so in the fall. Self-proclaimed rogue-economists, Levitt and Dubner apply economics to practical, everyday issue. The book tackles such questions as:

Which is more dangerous, a gun or a swimming pool? What do schoolteachers and sumo wrestlers have in common? Why do drug dealers still live with their moms? How much do parents really matter? What kind of impact did Roe v. Wade have on violent crime?

These two guys have done a great deal to popularize economics and generate some interest in the field. The stuff they study is fascinating. Note, I have a link to their blog (and website) under my "Other Sweet Blogs" section. Check it out. You will learn.
