It's about making our world work better!
This is a reminder that we must develop technologies and experiences in a way that serves people first!
Lot's has been said about Steve Jobs and how he was an innovator and leader of easier to use software and hardware. I think he was just somebody that asked the right questions and had the power to translate them into consumer products (well, impressive enough I guess).
The questions we all should ask more often - and we cannot be afraid to ask over and over again if we didn't understand - are WHY and WHAT. Only after figuring these questions out we are able to design, improve and innovate the HOW.
With that: Happy Usability Day!
