On the application of the basic metric identity in the analysis of the social web

The article considers the evaluation of the work of web networks of direct and reverse disseminations, which appear when describing the processes of production and social systems, tasks of the trade sphere, training, management. Each element of the network is considered from the position of fundamental characteristics of a matter - mutual dependence and conditionality of quality and quantity, which are connected by the Pythagorean fundamental metric identity and they give a chance to apply methods of mathematical physics in the analysis. Presented as an Appendix to the author's work [3].
