Blom, Robin, et al. "Frequent contributors within US newspaper comment forums: An examination of their civility and information value." American Behavioral Scientist 58.10 (2014): 1314-1328.

This study examines online commenting tools used by news organizations to enhance deliberation, focusing on the characteristics of contributions in newspaper forums. Analyzing 2,237 comments adjacent to opinion articles from 15 U.S. daily newspapers, researchers found that frequent contributors were less likely to post civil and informative comments. The findings suggest that diverse and civil participation is crucial for enriching dialogue in these forums.
