What have I learned about accessibility since the last time I was here?

According to Wikipedia: “The Dunning–Kruger effect is a cognitive bias whereby people with low expertise regarding a certain area of knowledge tend to overestimate their ability or knowledge.” I’m now fairly certain that, when I did my Appdevcon talk more than four years ago, I was overestimating my knowledge about the topic: accessibility. That doesn’t mean I didn’t know what I was talking about, but rather that there was sooo much I didn’t know that I didn’t know. But that confidence in my knowledge was probably what allowed me to finally overcome my fear of public speaking and deliver here my first-ever talk. It’s been a ride since then! And I’m ready to come back to update you on what I’ve learned since the last time I was here, with more knowledge and less confidence. We’ll focus on understanding that Accessibility is part of our job and everyone’s job. That there is much more to the cultural side than the technical aspect of it. That It is about customization, user choice, good user experience, and progress over perfection. And about being open to acknowledging that you don’t know everything, and that is ok, but that you surely care about all your users.
