Morten describes a future goal here. Certainly, it won't nor it shouldn't happen overnight, but I think the pace at which we get there lies somewhere between how fast we're going now and "radical," "aggressively" or whatever you'd like to call it.

This post and its comments have a lot of seeds for future growth around accessibility in WordPress:

If you're interested in accessibility, join the WordPress Accessibility team. You can do that here: http://make.wordpress.org/accessibility/ You don't have to be an "expert" either. Beginners welcome!

We know the current draft guidelines need work. Joe has been working hard on that. We'd love to get feedback from designers, themers, developers, theme reviewers (read: everyone!). Do that here: http://make.wordpress.org/accessibility/2014/06/12/theme-review-accessibility-guidelines-update/

Do you want to see more accessible WordPress themes? Joseph Karr O'Connor, the WordPress Accessibility Team rep, leads a project called Cities, meant to increase the number of accessible WordPress themes available in the theme directory. Join a team building one, or build one yourself. More info here: http://accessiblejoe.com/cities/

Justin: You're a well-respected WordPress developer and it's great to hear you're striving to learn more about accessibility. You've helped me a ton over the years with your excellent blog posts! I'm glad to return the favor. I'd be happy to review any theme you want to have the accessibility-ready tag and provide feedback from an accessibility perspective. The only catch? You have to blog about it! :) I think it could help a lot of developers in the community.

We just need to keep doing what we're doing. Making progress. There are many things that annoy me about WordPress – not just the fact that it's not as accessible as I'd like. I hate that we don't have a way to do content blocks. I wish the editing experience happened more in-line. The theme on-boarding process kind of stinks. And man, I wish I could output content in some other formats beside HTML so other apps can benefit from WordPress. But you know what? All of those things are being worked on or have been worked on recently. Let's keep moving.
