Metafic

In metafics, Janeites make hypotheses on the sources of inspiration for the novels, wonder how the world would have been without Jane, and imagine a TV talk show where Austen herself interviews her characters.

A few days later, the fan who sparked this discussion added her own voice to the debate with a metafic (that is, a fic about fandom) called 'The Girl Who Did Not Know Angst.'

This fic is considered a metafic, a fic about fanfiction and fandom, and usually metafic is satirical like this one.

The difference between this kind of "metafic" and objectionable "actor-fic" is that the metafic is still concentrated on the characters and the fictional world, with just a bit of the actors/real world (or other characters/other ficworld) stirred in for added interest, and usually humor. Objectionable "actor-fic" is fiction about the actors in the real world.

Depends. The blatantly obvious Mary-Sue-as-Metafic/Parody can be great, or it can be tiresome.
