My background is in biomedical research. Citing preprints seem to be an acceptable practice now, which are non peer-reviewed materials.
My question is: what about pubpeer comments? They are also not peer-reviewed. Although most of the time they are anonymous, and do not have a DOI.
Can, and should I cite pubpeer comments? How about academic social media / forum discussions? If I am not allowed to cite them, how do I properly credit their content?
