That is a beta test project. If you can't see it - it is probably more useful. Every page you go to you have to wait 30 seconds for the navigation links to be spoken. Not fun, not good, and very easily fixable. If you want to argue that with me, I'll show you my server stats.
Most web sites have extra lines and do-dads at the top of the page that literally do nothing.
With one link and alt tag those space and bandwidth wasters can be pressed into useful service. In this case - adding a link of this sort would always add, and never detract from your web site.
