    • AccessibleTwitter.com provides a web-accessible and standards-compliant version of the Twitter web site, a very popular micro-blogging web service.

  • www.AccessibleTwitter.com
  • Issues with Twitter.com
    • Many web accessibility issues including:
      • Some core functionality is not keyboard accessible.
      • Poor use of headings .
      • Much core functionality requires JavaScript .
      • Many more…
  • Keyboard Accessible
    • Keyboard cannot access Favorite, Reply, and Delete links.
    • ALL links are keyboard accessible.
  • ?
  • Use of Headings
    • Poor use of headings
      • Where are the tweets?
      • Can you find the menu?
      • What site is this?
      • Is my account info here?
      • Also:
        • Why is the footer under Following?
        • “ Saved Searches” is a primary heading but doesn’t display on the page.
  • Use of Headings
    • Ideal use of headings
      • Where are the tweets?
      • Can you find the menu?
      • What site is this?
      • Is my account info here?
      • *Names of Tweet authors are headings which greatly improves clarity and navigation for screen readers.
  • JavaScript
    • Twitter.com requires JavaScript. Without it, the user is unable to:
      • Favorite a tweet.
      • Delete a tweet.
      • Access the content under Trending Topics & Followers.
      • Perform core actions on Followers and Following pages.
  •  
  • JavaScript
    • Accessible Twitter is fully functional without JavaScript.
      • Progress Enhancement is paramount.
      • Hijax (Jeremy Keith).
      • Unobtrusive JS, of course.
  • Other issues with Twitter.com that Accessible Twitter addresses
    • Code doesn't validate.
    • Code could use better semantics.
    • Links unclear.
      • underlines removed
      • :hover pseudo class effects, but no :focus
      • poor color contrast
    • Custom colors may not be readable
      • MySpace syndrome?!
  •  
  • Other issues with Twitter.com that Accessible Twitter addresses
    • Sidebar navigation is inconsistent.
    • Form markup needs help:
      • Form fields are missing labels.
      • Fieldset tags used without legends.
    • Layout width is static not flexible.
  • Other Benefits of Web Accessibility & Web Standards
    • More usable .
    • Works in text-only user-agents such as Lynx.
    • Keyboard accessibility opens gate for many other types of input devices .
    • Providing clear, consistent content and navigation benefits those with cognitive impairments (and is more usable in general).
    • Use with a mobile device is possible.
  • Quotes from Users
    • “ You can easily navigate by several methods; skip links, form fields, headings. Very effective with a screen reader.”
    • “ really easy with a Braille Display to use”
    • “ From now on my default web interface for Twitter! Keyboard accessible == touch accessible!”
  • Quotes from Users
    • “… seems to work nicely in Lynx. Main Twitter won't let me login and mobile site won't show followers.”
    • “ Liking it more than twitter.com! Cleaner, easier, fun!”
    • “ Love this! So clear & Easy #dyslexia”
