I'd say it's been good for programming communities. It's improved productivity by a significant amount, meant far less hair pulling over tiny bugs and oddities and prevented a lot of wheels from being reinvented. That's especially good in less technical companies or ones with less expertise in general, since it means they can get more done without having to rely on third party developers or hiring extra employees. (it's also been pretty good for non programmers too, since the non programming Stack Exchange sites are filled with some rather fascinating questions and answers. Like the world building one).
