I notice that these are not in contradiction with adjectives that come to my mind first.. such as sterile, pretentious, mediocre, repetetive, heartless. Though now I think I'm kinda projecting properties into "flat design" it might not have, based on the properties I see becoming real hip in people.
I think you can only conclude that it's popular among trend-following designers... and I guess tech-turned-design-bloggers as well.
I'm really curious what the general public's perception is (not that it really matters) and if there are really any functional implications for the way some of the interfaces have been designed.
