This chapter explores how a network discourse has come to dominate certain approaches to exploring the informational global world and, more specifically, digital publics. These approaches, which encompass the work of some social theorists and management theorists, employ the network metaphor to tell us that a complex mixture of global flows. The chapter examines in a little more detail some ideas in complexity theory. The chapter also provides some common themes in and around complex networked digital publics. These public spheres are said by some to provide new innovative communicative spaces in informational societies for ordinary people to get their voices heard by others. A social scientist, draws on the ideas of Capra, a natural scientist, to similarly insist that globalisation is best theorised through the lens of complexity theory. Manson, S. M. (2001) identifies three schools of thought on complexity theory; algorithmic complexity, deterministic complexity, aggregate complexity.
