At times, it may be necessary to cite a comment someone has made on a blog entry, online article, social media post, etc. Generally, the comment will only be cited as a note, not in the bibliography, unless there is some significant reason you feel it should be considered a source on its own, separate from the work to which it was responding. Citation of a comment need only contain the name of the commenter (and/or screen name, as above), the date the comment was made (time stamp optional), and a reference back to the work to which it is responding.
