This post is the first of the new Simple Science category. This thread features research topics that are mainly focused on intuitive research facts/insight detected in the most important and well known virtual communities. However, research on complex networks is very interdisciplinary thus we do not exclude to extend our findings to other than social networks.
Since we want an audience as broad as possible and the content to be as readable as possible, we will not use strong statistical tools, but instead we adopt the basic and understandable ones. In special cases where more advanced mathematical methods are needed, we provide adequate and clear explanations.
