Mystery meat navigation (also known as MMN) is a form of web navigation user interface whereby the target of each link is not visible until the user points their cursor at it. Such interfaces lack a user-centered design, emphasizing aesthetic appearance, white space, and the concealment of information over practicality and functionality.[1][2] The term was coined in 1998 by Vincent Flanders, author of the book and accompanying website Web Pages That Suck.[3]
