This article focuses on the way five Belgian online newsrooms manage users’ comments related to the language of journalists. Three questions are addressed: are these online news comments filtered by the newsroom? Do they lead to some corrections in the articles? What kind of reactions do these comments trigger among administrators? In the matter of language, web users and newsroom members seem to share a kind of “no mistake ideology”. Nonetheless, professional constraints faced by web journalists make it impossible for them to reach their linguistic ideal. Even though the “proofreading” by web visitors is beneficial for newsrooms to some extent, the linguistic footprint of online comments, in visibility and influence alike, is limited by the newsrooms’ lack of interest in managing online comments.
