The widespread use of online interactive platforms including social networking applications, community support applications draw the attention of academics and businesses. We contend that the very nature of these platforms can be best described as a network of entangled interactions. A trans-disciplinary dynamic network analysis was conducted focusing on the largest connected component, so-called a giant component (GC), to better understand the network formation. The results of the analysis were the discovery of a phenomenon that the network has evolved over time with a particular pattern towards the emergence of the GC: The interactions of platform members coalesce into a GC with an accompanying approximately constant ratio. The network measures examined should be considered as novel and complementary metrics to those ones used in conventional web and social analytics.
