The article is devoted to the analysis of scenarios as conceptual structures of a specific type that underlie the pragmatic connectivity of stimulating and reactive messages as part of a blog text in Russian and projecting unison in the current interaction. It has been proven that these scenarios are an essential parameter of the linguistic competence of representatives of virtual communities and are used by the initiator of communication and its respondents to reach agreement and find a common semantic denominator for initially conflicting points of view. The authors dwell on the fact that the implementation of scenarios in computer-mediated communication is predetermined both by the formal capabilities of the lexico-grammatical system of the Russian language (discourse markers) and by linguocultural conventions that the interlocutors adhere to at one stage or another of the joint deployment of the blog text. In this study, the architectonics of scenarios for the connectivity of stimuli and reactions in the composition of the blog text is interpreted as a consequence of the implementation of relay structures. It is emphasized that the initiator of cohesion is the respondent (including the blogger in the function of the respondent) in the course of constructing a responsive message. It is shown that the pragmatic structure of these scenarios includes a foothold in incentive communication and a bond that docks with this foothold in reactive communication.
