FAQ: Must all questions be notable?
I know there have been a bunch of Meta discussions about whether answers to questions need to be referenced, and how good the references need to be, but there doesn't seem to have been as much discussion about how notable the questions have to be. The best Meta thread I found on it was this one.
Notable quote from Jeff:
The "just one thing" here is that someone must be able to point to a lot of evidence that people believe this, or that this claim is actively promoted. The idle daydreaming and "is it really true that.." has to be stopped.
I suppose I can understand wanting to avoid having totally random questions asked on this site, but I wonder whether the current threshold of notability about a claim has been set too high. It seems to me that StackExchange sites do best if they have lots of questions and lots of answers - helps keep the community active. There don't seem to be too many questions swamping the site right now, so why not allow even a relatively rarely-believed claim to be asked as a valid question? Never know, it might help some people out.
I asked this, and got downvoted for not having a reference. I later referenced Yahoo! Answers, but this was apparently not notable enough to make my question valid. I have also anecdotally heard this claim several times in my life. What would make my question valid? A link to a semi-famous celebrity posting the claim on Twitter? Their blog? Several blogs?
