Metapedianism is the philosophy of focusing on the internal workings of All The Tropes, including guidelines and policies, and social side of ATT, rather than editing articles and related content. Users who tend towards this philosophy are called metapedians and fall on the opposite end of the spectrum from exopedians. Mesopedians lie somewhere between the two.
Metapedians are often seen as the "social gadflies" of ATT, doing honorable work and civic duties: having general conversations on Talk Pages, taking part in deletion discussions and contributing largely in Wiki-Associations and places where discussion may be required.
They should not be confused with Metapedia.
