I can't find any Stack Exchange site where to ask questions about open-source in general.

I need to write a paper that explains the historical developments of open-source in a professional and legal way. Therefore it would be interesting to find some publications about experiences companies have had with open-source. I've been to FOSDEM where some companies present a positive viewpoint about open-source. A paper however is only objective if it gives a balanced view about several opinions. Does anyone know any publications about this topic, or a Stack Exchange site where I can ask this question?
