Our job as developers is to make the world a better place, whether it's connecting people, providing entertainment, or making someone's job easier. We have to know who we're building software for: our users. Understanding my users has been a key to every successful project I've worked on. I'll share some of my successes and some of my failures, and show how that's led to the approach to software that I take today. Together, we can provide our users with just what they need to make their world a bit better.
