I don&#x27;t think I followed any of these for my side project (www.diff.so) because, well, it&#x27;s a side project! It&#x27;s a prototype, something I did for fun. This is a great list of things to do before I expect someone to use it seriously, not a pre-launch checklist.<p>To go a bit off-topic, I actually tried to follow the &quot;don&#x27;t use color alone to provide information&quot; for the static diff on diff.so&#x2F;about, but I couldn&#x27;t find a way to get ChromeVox to read text on one side of the diff any differently than text on the other. I&#x27;d be really interested in any advice on that - it seems like some screenreader users could use something a little more user-friendly than emacs.
