github uses icon fonts without any kind of alternative background text, which is first of all a UX ugh (they are not particularly representational of anything, or in any way obvious), but relevant to this conversation makes getting to some of their page sections nigh-impossible with a screen reader. Also, not all of their JavaScript actions can be accessed without a mouse. I make the site work, but it's nontrivial. We could ask some of our screen reader testers if they would be willing to navigate to the bug site and find a bug that they had filed (in a test sense).

(although to be fair jira has been getting worse about accessibility as well, and I mostly like jira. I haven't used RT in while so I don't know what it's accessibility is like, but on the bright side if we were to try it out and add accessibility problems than we could (a) submit a patch or (b) send me down to the café where Jesse hangs out and I could poke him until he fixes it.)
