Social networks today are not just a technology and a "digitized" way of communication. The space of social networks has become the place of everyday life in which a modern person “lives”, spending a significant part of his daily time on various social platforms. Therefore, we are talking about social networks as a new digital everyday life or as its significant component. The choice of platform and features of online activity in social networks are determined by the affordances of the platform, as well as by the individual and personal characteristics of people. The purpose of the study was to investigate the individual ways of perceiving information and personal characteristics of users of various social platforms that are dominant in the digital everyday life of a person. The study involved 151 people (75 women and 76 men). Methods - author’s inquiry form about preferred networks and standard questioners. The results showed that the majority of respondents use one modality for perceiving and processing information. The differences between individual networks  are related to the affordances of each. Therefore, their choice as the leading everyday network is associated with the personal qualities of the respondents, and the main differences between them are determined by the Social self-esteem, Social courage and Extraversion scales. Users who choose Instagram and, especially, Telegram in all these parameters differ significantly from other users. Regardless the preferred network the priority of entertainment content is obviously shown. Instagram and Telegram users are more socially active, and more consciously build their digital space of everyday life in comparison with users of video hostings and, especially, with users of the VKontakte network.
