• Before making a single edit, Tropedia EXPECTS our site policy and manual of style to be followed. Failure to do so may result in deletion of contributions and blocks of users who refuse to learn to do so. Our policies can be reviewed here.
  • All images MUST now have proper attribution, those who neglect to assign at least the "fair use" licensing to an image may have it deleted. All new pages should use the preloadable templates feature on the edit page to add the appropriate basic page markup. Pages that don't do this will be subject to deletion, with or without explanation.
  • All new trope pages will be made with the "Trope Workshop" found on the "Troper Tools" menu and worked on until they have at least three examples. The Trope workshop specific templates can then be removed and it will be regarded as a regular trope page after being moved to the Main namespace. THIS SHOULD BE WORKING NOW, REPORT ANY ISSUES TO Janna2000, SelfCloak or RRabbit42. DON'T MAKE PAGES MANUALLY UNLESS A TEMPLATE IS BROKEN, AND REPORT IT THAT IS THE CASE. PAGES WILL BE DELETED OTHERWISE IF THEY ARE MISSING BASIC MARKUP.

There's a wiki for that.


It's Rule 78: There is a Wiki of it. No exceptions.

There is no area of interest, no matter how narrowly defined, where a person cannot put up a wiki for it and attract at least a few editors with similar interests. Increasingly, in fact, there is a chance that someone already has put up a wiki for it. For example, here's one for cacti. The plants.

In the early days of the Internet, there was a similar phenomenon, the "everything has its own home page" rule. Anyone with enough HTML savvy and a powerful enough interest in one particular subject could and often would create a site dedicated to it. This was largely how the early Web was forged, in fact. All the stuff we know and love today—e-commerce, social networking—that came later. Except porn. Porn was there from the beginning.

With the advent of Wikipedia, the playing field changed. Rather than rely on a collection of sites each written by one person with questionable expertise, users could find most of the information they needed in an article written, edited, and fact-checked by an entire userbase of people with questionable expertise, but all on one easy-to-remember site. The interest in hand-crafted "fan sites" waned.

However, a number of factors kept Wikipedia from being a perfect replacement for the old system. A desire for greater detail on the topic than Wikipedia is willing to allow, for one. Schisms or differing schools of thought on the topic was another. Fan-made wikis sprang up to bring back the world of homemade sites with the added benefits of the wiki model.

The "wiki-sphere" is becoming a vast depository of information at all levels of detail. The encyclopedic wikis are collecting a great breadth of topics at an increasingly shallow level of detail, and the topic-intensive wikis are gathering all the details.

Not all Wikis are on the major search engines, though. Corporations use wikis behind firewalls, the American CIA uses one to collate data among agents and analysts, and even publishers of dead-tree books use them to coordinate edits among authors, editors and copy editors.

Fan-made wikis are usually made on wiki farms, such as Wikia, or else are hosted on a preexisting fansite. Recently, organisations such as NIWA have spoken out against the commercialization that takes place on wiki farms, and have encouraged fans to set up their own websites.

Wikis can reach truly huge sizes. To put them up as candidate for a Doorstopper is an understatement. See the list of largest wikis. Note: If you're looking for TV Tropes, they're on the list at the bottom. "All The Tropes" hasn't even been noticed yet. The first list only has MediaWiki wikis.

Examples of The Wiki Rule include:


Anime and Manga

Comic Books

Fan Works

  • Sisterhood of Doom Wiki: For Desperately Seeking Ranma.
  • Averted for Undocumented Features, the fan work which is probably most likely to benefit from one. Primary writer Ben "Gryphon" Hutchins has discouraged a dedicated UF wiki for years on the grounds that one would likely bring attention to the work from intellectual property lawyers, which he would rather avoid.
