This small book is about the most popular (at least in RuNet) social networks and their brothers in the “social” family. In addition to such monsters as VKontakte and Facebook, there are many other interesting sites on the Internet built according to the “social” scheme: numerous forums and communities, popular blogs and even “bulletin boards”. All of them give you the opportunity not only to have your say on the Internet, but also to communicate, find new friends, create and create something new.
