I have observed in the past moderators closing the question because it is not notable enough, specifically posted on blog/social media that doesn't show much viewership.
However, others seem to be considered perfectly OK. Recent example:
The claim is sourced in a blog that, at first glance, strikes me as not quite notable or believed by tons of people.
What exactly is the rule for showing notability, in quantifiable terms?
To clarify: I'm not asking how the side decides notability (by having a moderating users VTC, duh). I'm asking what are the qualitative rules that a moderating user is supposed to use as a guideline for yes/no call on whether to close as non-notable.
Side question: Are those rules enforced consistently?
