Let me clarify my position while it may be a debatable point whether an Amazon review or a blog thread is a reliable source to use at Wikipedia I personally think it is given a supporting piece of evidence eg CALLING THE PERSON HERSELF OR THE OWNER OF THE BLOG PERSONALLY you are completely  wrong if you think she is actually NOT a dissident or that the review and blog postings attributed to her are not  hers    Um Tara can you double check with PZ that that post was actually from her Look at the wordingsyntax thats not how scientists write That looks like lincoln with gel in his hair  PZs not raised any red flags and the second quote was from the live chat The visit was to promote this new venture of hers Unfortunately I have no doubt its her  Posted by Tara C Smith  March    PM    Yeah Ill confirm it that was Lynn Margulis on the site and in the chatroom   Posted by PZ Myers  March    PM    That sigh was because I thought highly of Margulis she has done some excellent work and is always a source for original ideas Unfortunately the HIV denialist comments were all ignorant crap that only a deluded fool would find convincing So that was a sigh of disappointment  Posted by PZ Myers  March    AM    Furthermore I know form personal communication with Harvey Bialy that Lynn Margulis did communicate to him personally her positive review of the book So while the question of whats a reliable source may be some issue I just want you to know if happen to have any doubts that you ARE  completely factually wrong if you claim a her statements and viewpoints attributed to her are not hers and b she is not a dissident Unless you really believe that a mainstream biology professor is without any motivation committing some kind of hoax or is himself being impersonated by someone Thats what I was referring to when I said you were beyond hopeless
