The Wiki Rule

Go To

"There's a wiki for that."

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 pornography. Porn was there from the beginning.


With the advent of Wikipedia, however, the playing field changed. Rather than rely on a collection of sites each written by one person with questionable expertise, users could now 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.

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. Wikis are also popular with open source software projects for documentation as wikis can be updated much more quickly than static pages.


The "wiki-sphere" is becoming a vast depository of information at all levels of detail. The encyclopedic wikis are collecting a great breath 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/FANDOM/Wikicities.note  Few are hosted on preexisting fansites, like &


Recently, organisations such as NIWA (Nintendo Independent Wiki Alliance) have spoken out against the commercialization that takes place on wiki farms, and have encouraged fans to set up their own websites, while The Anti-Wikia Alliance is against Wikia specifically.

Wikis can reach truly huge sizes. To put them up as candidate for a Doorstopper is an understatement. See the list of largest wikis.

Also, due to the ever-increasing importance of wikis in modern internet culture as well as the ever-increasing amount of information stored in said wikis, several archival initiaves such as the Wiki Team by Archive Team (which in and on itself is a wiki) have sprung up in order to protect these valuable codexes of information from maladies such as expired domains and wikifarm shutdowns. Show them some love.

The "dead tree" equivalent of this trivia is The Magazine Rule.

Please alphabetize examples by what the wiki is dedicated to rather than by the wiki's name.
