InfoWorld has a special report on new ideas being forged by open-source software:
Across the software industry, countless developers, individuals, and companies are experimenting with open source methods. One reason is because community-driven development allows a software product to grow organically. As Eric S. Raymond observed in his seminal work, The Cathedral and the Bazaar, Every good work of software starts by scratching a developers personal itch. When a group of developers begins to collaborate in an open fashion, each one scratching a unique personal itch, the result is software that expands to fill those functional areas not addressed by proprietary offerings.
