Introduction. The research analyzes 6 scientific and pseudoscientific magazines in terms of web 2.0 tool usage and informational treatment. Methodology. The digital ecosystem of the magazines is explored and described, and subsequently a quantitative and qualitative content analysis of 232 units is elaborated. This sample is probabilistic and selected randomly from a universe of 1,434 publications of the magazine's web, Facebook, Twitter, YouTube and Instagram accounts. Results and conclusions. The results show that use of 2.0 resources is basic and features of social networks are hardly exploited. In addition, although many images are used, news are not accompanied by videos, info-graphics or other types of interactive resources. The information treatment presents a need of improvement, more news should be accompanied by their authorship and the source of images more often captioned.
