Complex networks can be described as a sub-area of physics and mathematics, where you study how things entangle with each other. After Barabasi and Newman (in my personal point of view) complex networks spun across multiple discipline areas. They also brought quantitative tools in understanding traditionally qualitatively evaluated social sciences.
Some questions may well refer to tools and practices, like similarities in networks sciences (cosine, Jaccard, Newman, etc.).
But personally I would mostly see useful this site to help multi-disciplinary fields in using complex networks as a model.
An emergent science would be science of ecosystems, and complex networks could help in model ecosystems as hyper-graphs or multi-partite graphs between multiple types of edges and types of entities.
Another aspect, is to mark a broader scope from definition of network confined in communication theory. As a consequence, I would definately use this site to better understand how information and entropy can be described by a network - Shannon and Prigojine put some landmarks but sciences are inquiring beyond that.
As example, networks could be messages storing information, some studies proposed that to apply consider crystals of minerals as network carrying geological information; other books proposed networks in economics.
But a better understanding of applying proper model is necessary, because I except that disciplines in biology, econonomics, social sciences, technologist experimenting in block-chain and self-organisation, may lack a background specialised in complex networks and definately this site would be of help.
I would like to see questions broader from technical aspects, that may help OPs in defining models and properly applying network theory to describe their object of inquiring.
Based on this, my question is if a broader description of complex networks as ecosystems would better address the purpose of the site, and beyond the title how to make a sufficient distinction, to average user, that complex networks is here embracing a wider area than a sub-branch of physics.
