I understand that nothing gets people yelling at each other like a meaty discussion on accessibility, but I’m not getting why the idea of making alt optional on img tags in HTML5 is causing such a furor. The alt attribute is the lowest of the low‐hanging accessibility fruit, and the number of people on earth who care about valid HTML — but don’t care even a little about accessibility — could fit into my pants. Get more people interested in validating their HTML; then we’ll talk.
