I have had this book for many years and often use it for referance, but over the last week i read it from cover to cover (again). It really is a great book, with good insight for software professional. The posts printed within are mainly from 2000-2002, but none the less the messages and thoughts still hold true. Although he does amusingly get a few predictions wrong. If your into software this is a must have book. Also don’t forget to visit Joel on Software
