Here is a question I had in mind (that was closed).
It began by asking how the quality of a screenplay is judged by the Oscar panel. That's certainly an expert, authoritative source. It then rambled a bit before I brought it back to the main point (with an edit.): "Are there any authoritative sources that spell out how to evaluate screen plays?"
Now, I'm not particularly interested in "layman" opinions about how to evaluate screen plays. But selections made by an Oscar panel are "factual," and the underlying reasons, although technically "opinions," are "expert." And there is a group of professional writers (some of them future Oscar panel members) who are paid to teach people how to write to maximize chances of Oscar selection.
On the history site (where I am a high rep member), I opined that the views of a recognized historian such as Stephen Ambrose could be treated as a "fact" (about Stephen Ambrose. https://history.stackexchange.com/questions/8615/why-did-stephen-ambrose-believe-that-the-election-of-aaron-burr-would-have-led-t) Would it make sense to do the same on this site by treating pronouncements by "authoritative" sources on this site as fact?
If so, can we reopen the question?
