According to Chicago Style Manual (16th ed.), "Citations of blog entries should include the author of the entry; the name of the entry, in quotation marks; the title or description of the blog; and a URL. Citations of a comment should start with the identity of the commenter and the date of the comment (if a time stamp appears with the comment), the words "comment on," and the citation information for the related entry....Blogs that are part of a larger publication should also include the name of that publication. Add the word blog in parentheses after the name of the blog (unless the word blog is part of the name). Citations of blog entries are generally relegated to the notes; a frequently cited blog, however, may be inlcuded in the bibliography."
