In the name of all that does not suck, I beg you to NOT do "flat design". Make it possible to navigate a website - make hyperlinks blue, underlined text. Have visual cues for buttons. Have buttons, not magic pixels. Don't hide information in "hover over" things.
Is this humorous? Is the joke that OP can predict that in-progress designs will be one of two options, because ‘every website’ uses one of those options?
