Exopedianism is the philosophy of focusing on the trope and work page side of All The Tropes (articles and related content) rather than the social and institutional side of the project. Users who practice the philosophy are called exopedians and fall on the opposite end of the spectrum from metapedians. Mesopedians lie somewhere between the two.
Exopedians may seem cold and aloof to some other users, due in part to a personal focus on contributing and editing content on ATT rather than interacting with users. However, they may interact on certain internally related areas of ATT when articles they are focused on are altered in some fundamental ways: merging, deletion, etc.
