Not all blogs pretend to be journalistic or related to current events in the sense shared by institutional media. In fact, most blogs are mainly personal and revolve around the feelings and experiences of the author. However, any blogger can “commit journalism” when describing or analyzing an event he/she has witnessed. In addition, after blogs became a buzzword within institutional media, some individual journalists also embraced them as a new, more open way to communicate with their audience. Subsequently, media companies themselves have explored the possibilities of this format as a journalistic genre and as an open space in which web users can participate. Even if bloggers writing about current events may not feel comfortable comparing their publishing to journalism, we argue that this heterogeneous group of weblogs, some made by the public, some by journalism practitioners, and some by media houses, have something in common that justifies the label ”journalistic weblog”: Although they may not strictly follow traditional journalistic routines and conventions, these weblogs have a clear intention to collect, analyse, interpret or comment on current events to wide audiences and in this way perform the very same social function usually associated with institutionalized media.The main purpose of this study was to compare press journalists to blog journalists, according to journalists bloggers. This research method survey and questionnaire was conducted. The population comprises of all blog journalists working in newspaper portals in Tehran. We used Simple Random Sampling in this study.
