Same, I understand the editors/admins can't be experts on every topic but just because THEY don't think something is notable doesn't mean most people don't either.

In general, it should be clear from the article if the subject is notable. Admins don't have to be an expert, they just have to read the article.

Notable is not the same as popular.

Notability is arguably even more subjective than popularity.
