Yes, you attacked my view on WP/AN/I.  However, one does not establish credibility by what "looks credible," one offers arguments and supporting evidence as to why it's credible.  You agree it's a professor's vacation blog.  Blogs are not considered credible sources on Wikipedia.  See WP:Verifiable:
"Anyone can create a website or pay to have a book published, then claim to be an expert in a certain field. For that reason, self-published books, newsletters, personal websites, open wikis, blogs, forum postings, and similar sources are largely not acceptable.[5]"
