Blog entries are cited like newspaper articles and may also be cited in the running text instead of in a note, bibliography, or reference list (i.e. "In a comment posted to The Becker-Posner Blog on February 16, 2012..."). If it is not obvious that the source is a blog post, follow the title of the blog with (blog).
When citing a reader's comment, do so in terms of a shortened version of the original post, which has to also be cited in full elsewhere. Cite the name of the commenter as it appears with any identifying information following in parentheses, followed by the date of the comment.
