After reading the diverse chapters in this book, I remain fascinated but still skeptical about how important open source actually will be in the long run and whether, as a movement, it is raising unwarranted excitement among users as well as entrepreneurs and investors. On the development side, I can sympathize with the frustration of programmers such as Richard Stallman, Linus Torvalds, or Eric Raymond in not being able to improve commercial software and thus determining to write better code that is free and available.
