Explanation

This comic illustrates the "problems" of information explosion coupled with a dense web of hypertext links. Through most of human history, written media has been both slow and linear. Hypertext allows a new type of information consumption, through small chunks of information linked together in a web of related concepts, and by being digital, each new chunk can be retrieved quickly and effortlessly. Wikipedia applies this principle very strongly, and because it covers so many topics, it is common for a reader to skim an article about a topic they need or want to know about, and end up following a series of links out of curiosity. Since each new page also has several links, the overall navigation pattern resembles a tree that branches out, "exploding" in size with each new level of link-clicking, thus resulting in many trivia-filled hours (over three in this case) of reading stuff unrelated to the original goal, and lots of open browser tabs holding a wide variety of articles, which are seemingly unrelated, but have common "ancestors." (The problem, for Randall, of wasting time on Wikipedia was later referenced in the title text of 1501: Mysteries, and the more general problem of getting trapped following a never-ending chain of interesting links was covered in 609: Tab Explosion.) The large diversity in end links may also be a reference to the Wikipedia game.

One can also see this effect occur in other MediaWiki-powered wikis such as this very website, where one comic can lead to another of similar relation or category. In the table below, a possible route for each entry has been found.

Finding routes between the start and end points of the two pages above and the six below makes good challenges in the Wikipedia game.

The title text refers to two of the articles that were supposedly reached at the bottom. William Howard Taft was the 27th President of the U.S., in office from 1909 to 1913, who was notorious for being so overweight that when a White House chief usher invented a story about him getting stuck in the White House bathtub, people took it seriously. A wet T-shirt contest is an exhibitionistic competition typically featuring young women contestants at a nightclub, bar, or resort. Clearly the combination of these two would be rather bizarre.

There is an online game that involves trying to get from one Wikipedia page to another in the shortest possible route: http://thewikigame.com/.

Table of paths

Due to the ever changing nature of Wikipedia, the Tacoma Narrows Bridge entry on Wikipedia no longer links to Structural collapse, requiring an intermediate step via Tacoma Narrows Bridge (1940), and since Structural collapse now redirects to Structural integrity and failure, most pages on Wikipedia that linked to Structural collapse have been changed to rename this link.

The table below lists one valid route for each destination article, though it is not necessarily the most efficient route. And that these routes may become invalid as articles are edited. They all have been updated on March 21, 2015. All links then could be found directly on the page. This was not the case in the original version of the paths, where some links were in hidden parts of the page.

Target Wikipath
William Howard Taft Tacoma Narrows Bridge > World War II > Paris Peace Conference (1919–1920) > Washington Heights, Manhattan > George Washington > William Howard Taft
24-hour analog dial Tacoma Narrows Bridge > United States > Coordinated Universal Time > Clock > 24-hour analog dial
Lesbianism in erotica Tacoma Narrows Bridge > Paramount Pictures > X rating > Lesbian erotica
Fatal hilarity via Batman Tacoma Narrows Bridge > Suspension Bridge > New York City > Washington Irving > Batman > Batman (1989 film) (this extra link now needed to go to the final page) > Fatal hilarity (this page now redirects to Death from laughter. On the previous page the link to that page is called die laughing)
Taylor Hanson Tacoma Narrows Bridge > Paramount Pictures > NickMusic > Total Request Live > Taylor Hanson
Wet T-Shirt Contest via T-Shirt and Cotton Tacoma Narrows Bridge > Tacoma Narrows Bridge (1940) (this extra link now needed to go to the next page) > Structural collapse (this page now redirects to Structural integrity and failure and is also called this on the previous page) > Maharashtra > Cotton > T-Shirt > Wet T-Shirt Contest
