Why Open Source
The Open Source community attracts very bright, very motivated developers, who although frequently unpaid, are often very disciplined. Authors are motivated by pride and peer recognition rather than a development plan supplied by the marketing department. Most want to use the software themselves and they prefer robustnesss before adding features, hence some Open Source developers are amongst the most experienced in the industry.
