On the other hand, sometimes it is aspirational, in the sense that the creator hopes that having a place for people to post will lead to discoverability. One day someone may come across it and decide to post just because it is there.

Cautionary Tales
We tell our children unsettling fairy tales to teach them valuable lessons, but these Cautionary Tales are for the education of the grown ups - and they are all true.
