:When an associate producer tightly related to a subject writes an article, even in a reliable source it is still a self-pub, and if you go just a bit further down the page you have linked to, you'll note that WP:SELFPUB explains that such sources should not be used if the material is self-serving (a notability claim would be self-serving if it is in the author's financial interest), it involves claims about events not directly related to the source (award notability is a claim about an event), or the article is based primarily on such sources (it is).  It is not a case of feeling he has too much personal knowledge.  It is that he has a direct financial interest in the success of the subject.  His personal knowledge being reflected in his writings should not be used to establish notability - it can be used to establish non-notable facts, but not as a basis for notability.  Using it as a basis for notability is akin to a reporter writing an article about themselves being a notable reporter.  We simply would ignore such claims unless independent reliable sources existed to support such a claim, and if those were the only claims of notability without any verifiable independent reliable sources discovered such an article would be deleted.
