Blink was good. It got a lot of criticism because people felt that it didn't really answer the questions put forth in the book. But I felt that it did a good job drawing attention to the facts. I also liked the variety of topics discussed.
Read Blink first then started reading the Tipping Point. Didn't make it through the first chapter... Not because it was boring.. But because I got distracted by another book... I'm sure I'll go back to it eventually. But this is supposed to be the fore runner and more well known piece.
