Web fact no. 4:

Mystery Meat Navigation is a Ghastly Means of Navigation

While there are 10 million ways to screw up your navigation, the best way to screw it up is to use Mystery Meat Navigation (MMN).

What is Mystery Meat Navigation you ask? Web Pages That Suck defines it as:

"Mystery Meat Navigation occurs when, in order to find specific pages in a site, the user must mouse over unmarked navigational "buttons" - graphics that are usually blank or don't describe their function. JavaScript code then reveals what the real purpose of the button is and where it leads."
