Abstract: As a grassroots medium, blog assumes a paradoxical peculiarity in its propagation form:it is a private discourse yet it spreads openly; bloggers are readers on net and web authors as well; each blog is at once an independent system and capable of conducting group interaction among systems. Though the emergence of famous bloggers in large numbers will not inevitably shake the base of common people’s grassroots medium to its foundations, yet the so-called grassroots medium with blog as its rep is qualified by a certain technical or economic level and therefore it cannot be taken as a folk discourse channel in its true sense. It calls for the common efforts of grassroots and conventional media to foster the kind of media democracy that is really widespread and that strikes roots in people’s hearts.

Key words: blog, grassroots medium, landscape, phantom, democracy of mass media
