Robert Cooper has connected the dots on two different different facts: there are 139,834 projects on SourceForge and new advanced search facilities – like Koders and Google Code Search – make all of them accessible.
Tthe general perception was that the vast majority of open source projects were dead ends that served no particular purpose. But that’s no longer true. All coders need to do is write good comments and the code can now be found and reused.
This means that open source projects can benefit from the Network Effect. The more diverse projects and the more code, the more useful the repository becomes.
