I don't understand why fans think just because you post your opinions on Youtube, you suddenly become a credible and quotable source. sFdebris' opinions are no more credible than Snooki from Jersey Shore giving a review of Star Trek.
I don't understand why you think you can quantify quotability. If someone says something you like or agree with, and the quote is relevant to the present, then that person is quotable. Publishing your thoughts publicly, such as on Youtube, absolutely does
make you quotable.
As for credibility, you were doing good until you mentioned Snooki. As I'm reasonably sure that sfdebris is more familiar with the material than her, it's definitely false that her opinions would be as credible.
