""At three in the morning I looked at my clock and thought, 'Good god! What on earth have I been doing for four hours?!' I looked at my screen. 'Plot summaries of Power Rangers episodes.' Damn.""

The Other Wiki. The wiki that most people are familiar with. The one that isn't us.

Wikipedia is the most famous wiki out there, and is mostly responsible for inspiring the creation of other wikis (although it was not the first). It presents its information as an encyclopaedia and focuses mainly on real-life information.

Given Wikipedia's role as a central information source, you can probably gain more info on the "what" of (for example) Star Trek from it than you can from actually watching the show, and that's nice. Here?

Here, you can get a glimmering of why the show is like that.

Here at TV Tropes, we only care about how things apply to fiction. Don't just tell us the facts; tell us the memes, tell us the archetypes, tell us the catchy ideas and symbolic roles that get planted in people's heads. Got the kernel of an idea bouncing about your head? Throw it down here and see what grows. If we're lucky, our Neologism for it will catch on.

Wikipedia has an entry on itself and its history, for further reading.

Wikipedia also has an entry on us. It also lists us in its directory of alternatives, encouraging people to record their trope knowledge here, instead of there. See the We Are Not Alone Index for tropes that have Wikipedia articles.

Wikipedia provides examples of:

 * Anthropomorphic Personification: Wikipe-tan, specifically Moe Anthropomorphism.
 * April Fools Day: Since the very beginning, April Fools' pranks have run rampant on Wikipedia, even by established editors. See a list of them here.
 * Captain Obvious: Wikipedia's attempt to be a thorough information source presented in an easy, accessible format while maintaining a dry and formal tone of language sometimes leads to some unintentionally hilarious examples of this.
 * Common Knowledge: The pop-culture version of Wikipedia is overflowing with ridiculously phony and inaccurate information ("George W Bush is a time-traveler from the year 3000 sent back in time to fight the Martians from the planet Venus!") Quite unlike the real-life version, it appears to have no blocking or vandalism policies whatsoever.
 * Conversation in The Main Page: Averted hard and fast - this usually survives minutes, at most.
 * Cowboy Bebop At His Computer: Anyone can add anything, whether it's correct or not. Depending on the subject it may be corrected within minutes or it may stay for quite a while before it's noticed and corrected.
 * Defictionalization: Wikipedia has proven itself correct at least once.
 * Digital Piracy Is Evil: Apparently FBI threatened to sue Wikipedia for using its logo.
 * Drive By Updater: In an odd twist, even useful drive-by-edits are sometimes reverted.
 * Dr. Pedia and Mr. Trope
 * Edit War: Due to its size, these are just as likely to occur between administrators as between regular users.
 * Encyclopedia Exposita
 * Fancruft: Referenced by Xkcd (again), and occurs in reality on some pages. The page for Earth used to have "DO NOT REPLACE THIS PAGE WITH 'Mostly harmless.' EVER." hidden in the markup. It still has "Humorous references to the Douglas Adams novel Mostly Harmless are inappropriate content for this article" on the talk page, and is semi-protected so that only registered users can edit it (for several reasons).
 * Fannage: They have, for instance, plot summaries of every single Star Trek episode - all series. Their coverage of The Simpsons is also impressive, with about the half of the articles on that series rated either "good article" or "featured article". Though in a perfect example of serial deleting in action there's currently a discussion of the idea some guy had to 'merge' (delete) all the Enterprise episode pages so instead of the detailed summaries which currently exist there is a couple of sentences for each.
 * Fauxtivational Poster: WIKIPEDIA / Find your own damn sources.
 * Follow the Leader: The wiki craze started here, but this was not the first wiki. The Ur Example was Ward Cunningham's Portland Pattern Repository.
 * Great Big Book of Everything: And how!
 * Iconic Logo: The puzzle globe dates to 2003; its first iteration had the pieces in different colors and blocks of text, in different languages, on it. Shortly after that, the more familiar version of the globe debuted, with all of the pieces light gray, and each having a letter/glyph on it. It stayed this way until May 2010, when a new version (which, unlike its predecessors, was an actual 3D rendering), with a darker gray, bigger pieces and corrected symbols on two of them, debuted; this is the one pictured above. It was revised again later that month, when the shade of gray was lightened to resemble its predecessor.
 * Kuudere: If anyone's curious, Wikipedia does have a fun side to it. Enjoy.
 * Lumper vs. Splitter: Wikipedia's guideline on lumping
 * Locked Pages: Several forms, often involving different levels of user access required to edit.
 * Meido: The various maintenance bots are sometimes personified as such.
 * Moe Anthropomorphism: Yes, they have their own one. In this case: Wikipe-tan.
 * Our Super Strict Language Policy: Very similar, minus funny being acceptable.
 * Pothole: Sometimes taken to ludicrous extremes - at least early in an article about a complex topic. They call it a "piped link" or "piping", after the | character in the Usemod-inspired syntax that potholes on MediaWiki use.
 * Serious Business: The major two factions on Wikipedia are the Inclusionists and the Deletionists, as mentioned in the introduction. Deletionism was, for some time, the primary school of thought of Wikipedia--even against the wishes of its founders. Just look at the flame war that kicked up when Jimbo Wales tried to start an article about a South African restaurant, only to have it deleted almost immediately. In addition, reading discussion pages on any topic is likely to result in a lot of Serious Business.

Unfortunately, besides the serial deleters, there's also a phenomenon of 'page hoarders' who will sit on a certain page and revert and delete any changes made to it, and will spend all day arguing about it until the admins give in to them. Forget Wiki Vandals, these guys are Wikipedia's biggest problem. Counter-Vandalism Unit, seriously, just... take a look at what they made up.
 * Sesquipedalian Loquaciousness: Played straight in some more technical article and inverted in Simple English Wikipedia.
 * Small Reference Pools: One of the major underlying causes for conflict between Inclusionists and Deletionists, as well as systemic bias (see We All Live in America below and Serious Business above). If a Deletionist hasn't heard of something, it's obviously non-notable.
 * Someday This Will Come in Handy: Has been known to cause attempts to invoke this trope.
 * There Is No Such Thing As Notability: Utterly inverted.
 * Thread Mode: The bullet points version is averted hard in articles but played straight on talk pages and deletion process pages. The inline version, not so much.
 * Trope Codifier: The MediaWiki software developed for Wikipedia and the style conventions set there have set audience expectations for reference wikis.
 * Trope Overdosed
 * TV Tropes in Other Wikis: We have a page.
 * Troll: Some people put either totally irrelevant things on the page (sometimes wiping the whole page in the process) or mess it up by doing the summary wrong.
 * We All Live in America: Many pages can turn into this, deciding that only information pertaining to America is useful. Especially jarring on pages meant for other countries entirely. Amusingly, there's a template specifically for flagging a page as being Americacentric (or Britaincentric, or other part of the world-centric). This can be applied to pages specifically written in reference to the country.

They have a phrase for this: Systemic bias. It's not a problem limited only to English Wikipedia articles on North America, Great Britain, and Australia. Any sufficiently developed country with widespread use of English will have a significantly larger group of contributors than its non-English speaking neighbors. Hong Kong, Singapore and India being notable examples
 * Weasel Words: They hate it when it shows up.
 * Wiki Magic: Sometimes played straight, sometimes inverted with an editor's pet page. Inversions of this have rapidly become a common criticism as Wikipedia's tendency to focus on cutting as much content as possible, instead of adding new content, has increased.
 * Wiki Vandal: Overt vandalization is reverted rapidly - but subtle vandalization has been known to last months on less-travelled pages. One of the common complaints about accuracy aimed at Wikipedia. Some really outrageous claims in articles are often supported by nothing but the "citation" tag.[citation needed]
 * Wiki Walk: See Archive Binge above.
 * Wikipedia Syntaxer: The original and trope namer.
 * Wikipedia Updater
 * Xenofiction: Well, except the "fiction" bit. The Human article reads as though it was written by alien scientists observing us. It even lists the conservation status according to the IUCN red list: "least concern".
