Davis Wiki isn't very accessible. Tenon.io has a report for Davis Wiki that shows accessibility issues including that form elements are missing labels and that images don't have alternative text. You can paste links to other pages on the site in and see how they do.
Accessibility is important for everyone, not just for blind folks using screen readers. Accessibility also covers making sure that folks who have mobility impairments can use tab and enter to navigate, and drives the design of buttons and link sizes so that even a drunken undergrad in search of hella-cheap cheezy-fries can find them at 2:00am.
