Re: A serious question.
One gem of the flat style is the so-called hamburger menu. On a reasonable design if you have a link which expands to give a choice it will at least be labelled "Menu" and might even be in the form of a button. Or it might even be a series of first level items on a menu bar - much like our beloved "DATA CENTRE SOFTWARE" etc menu across the top of elReg and each then dropping down to give more choices. With a hamburger menu you get 3 short lines, supposedly a schematised drop-down list but looking equally like a schematised hamburger. This will be lurking in an odd corner somewhere and quite possibly looking much like some of the other irrelevant bits of graphic design on the page.
