Typical models of human communities often involve networks consisting of several individuals connected by weaker or stronger ties. These networks provide a structured pathway of signal transmission through the community. In the modern information society, however, one observes a different type of community, which lacks a clearly defined and consistent structure. This paper presents a computer model of one such tie-less community, in which individuals pass the signal to random peers in random moments of time. Several simulations performed with the use of this model reveal that the tie-less community has interesting properties which are analogous to certain phenomena that occur in typical networks, including percolation, phase transitions and self-sustaining oscillations.

In the article, three basic types of strategies for sociological theory construction as well as main features of model-based strategy are briefly introduced. The main attention is payed to the road passed by contemporary analytical sociology in the field of theory construction. Theoretical models (drawn from R. Boudon´s work) based upon social mechanism and providing explanation of social phenomena or processes, correspond to the first step on the road. In the next section, the transitional stage from theoretical models through classic formal models to agent-based models is mentioned. As a common example, the reproduction of social inequalities (Matthew effect and cumulative (dis)advantages) which constitutes the substantive background linking classic formal models to agent-based model was exploited. The final part is dealing with the construction of agent-based model of deference exchanges (Manzo & Baldassarri). Heuristic and methodological problems are emphasized.
