[A 404 page] is the feeling of a broken relationship.

Source: "404, the Story of a Page Not Found." TED2012. Feb.2012. Conference Presentation. Additional Information: This quote is from a 2012 TED Talk given by media strategist Renny Gleeson about how several companies took advantage of the "404 error" page on their website and used it to connect with customers in a meaningful way. A "404 page" is the default page that loads when you ask a website for something it can't find. The quote means that encountering this page is disappointing and gives you a feeling of disconnection; it damages the relationship you have with the website you are trying to reach and the brand the site is associated with.
