Flat design is still pervasive, and has horrible ergonomics. If I'm supposed to click on something, make it look that way, OK? Also, a tiny, grey chevron on the far right of some text is not adequate for marking a pull-down list. Who thought any of "flat design" was a good idea, and did they have to black mail all the human factors people to get it in production?

All that to say, I emphatically agree. Lemmings following a trend is not a good way to distinguish anything or any one.

Do you have a good example of a website that does not follow flat design that you like?
