It's literally in the word - it is a listing of fans. This is a common concept, but it was popularised into an online phenomenon by the creation of an unofficial, voluntary organisation, The Fanlistings Network (TFL) in 2000, and has now expanded to listing thousands of diverse fanlisting subjects - from TV shows, to foods, musicians, etc. There are no costs to join a fanlisting (financial or otherwise); the only requirements are your name and country, and often e-mail. Fanlistings are voluntary fan projects, therefore they are usually only recognised by TFL and *not* by any official, profit-making organisations centred around the fanlisting subject itself.
