  == Article: Expelled (2008 movie) Subject: Considering a blog as a reliable sourcee ==  I realize that the author of that blog is a distinguished professor in the field of biology/evolution. However, that title does not automatically verify his claims about the screening cancellations. Had he had said something about evolution/biology or anything else in the field in which he is distinguished for, his blog entry would have more weight.   However, his position is irrelevant on what he has posted when it comes to verification. He is no different than a regular movie goer who posted the same account on his/her blog.
