Hmmm, 15 years, but I have never heard of Neotribalism - so thanks :)
The one thing that I've never seen before is the clear definition of the protagonist and antagonist in the epic battle of skeuomorphism vs flat design: Leather Weirdo Forstall vs Good Taste Ive (e.g. [1]). IMHO that made it much easier to divide people into camps (tribes?). And as if that wasn't enough, Apple used the keynote to feed the fire and polarise.
You must be new to the Internet. Allow me to show you some pictures of cats and a video of Charlie biting a finger.
I saw the term Neotribalism on HN this morning. This perfectly defines much of the designer elitism that runs rampant throughout the design community.
