A nicely written, clear and solid article on software development in the Free (Open Source) Software distributed model. Which is one of the possible development models (roughly, the Bazaar).
Definitely worth a mention. Have a look at the article How Open Source Software Can Save the ICT Industry One Trillion Dollars per Year., by Micael Tiemann (Creative Commons by 2.5, I believe, but check with the author). Some further notes at http://www.opensource.org/node/384 .
My favourite quote:
The most significant transformation in ICT has been the emergence of Free and Open Source Software (FOSS). Consider the popular internet as embodied by the World Wide Web. This vision was first published by Vannevar Bush in 1945, and prior to 1990 there had been dozens of attempts to create such systems, the most popular being the French MiniTel system But none of these systems became truly ubiquitous until the underlying software was free as in freedom. The freedom to read, modify, and share web server and client code led to an explosion of innovation, and to date the most popular product of that explosion, the Apache web server, remains dominant in spite of considerable efforts by some powerful companies to take over that space. This came as no surprise to Tim Berners-Lee, creator of the World Wide Web, who explained his decision to make the original web software free and open:
[H]ad the technology been proprietary, and in my total control, it would probably not have taken off. The decision to make the Web an open system was necessary for it to be universal. You can't propose that something be a universal space and at the same time keep control of it.
