To me Linux is the mother of all open source software/platform/stack/OS and Social networking concept and platforms.
Over the years, we have learnt how to work effectively and efficiently with in the norms of a community. This knowledge triggered¬† a plethora¬† of ideas to folks to actually follow the path laid by Linux community to develop so many other software stacks. The whole concept of community development drove hordes of people to think of networking online or in today's words - social networking. In my opinion Linux have had a positive influence on society at large to actually create sense of togetherness and unity among people from all walks of life. For once we should all be proud of Linux's accomplishment to treat every one equal irrespective of race, color, caste, creed or religion.¬†
