From slashdot :
Open-source software companies, such as Ubunutu (an open-source Linux distribution), are better able to respond to user request and bugs than traditional software companies, such as Microsoft. Simon Law, head of the Quality Assurance department at Ubuntu in a talk given to the UW Computer Science Club, explains why this is, and how Ubuntu is leveraging the open-source model. Simon explains how the QA department at Ubuntu differs from traditional QA departments, through its use of the open-source community at large. Most interesting is Simon’s views on what motivates open-source developers to develop software, and how open-source oriented businesses (specifically Ubunutu) are making money.
