@Sh41 There wasn’t one such a case for me, as far as I remember, more of a process, although I cannot downplay the importance of @laura’s influence (if you haven’t read it, check out her book Accessibility For Everyone). Once you learn what accessibility means, it just takes a bit of empathy to realise it’s not a ‘nice to have’. As far as I’m concerned, it’s part of good design, not separate to it. And the reason I care about good design is because I care about people: http://www.breakingthin.gs/this-is-all-there-is.html
@aral I'm curious how you became invested in accessibility. For most of us there's usually some event or person that opens or eyes, and then we can't stop caring about it anymore
