I have found no "trend" in the blogs, and no one has established a "trend" in the blogs. They are blogs, not research articles (it's explicitly stated that research articles must have APA annotation).

I've read several blogs pertaining to CEN, and they espouse a variety of POVs. Furthermore, what constitutes an "offensive" blog? Is it a blog that you disagree with the author's POV?

As for the blogger's credentials, I believe it's important to list the credentials of the blogger for transparency.
