What Business Can Learn from Open Source

It's an interesting essay on What Business Can Learn from Open Source from Paul Graham. From the essay: "But the biggest thing business has to learn from open source is not about Linux or Firefox, but about the forces that produced them. Ultimately these will affect a lot more than what software you use. We may be able to get a fix on these underlying forces by triangulating from open source and blogging. As you've probably noticed, they have a lot in common."
