Something that came up yesterday when I was discussing with User:Rexx about the new WikiFont, is how it will influence accessibility, since it is actually a 'character' that will have effects on screenreader software. I have no idea what the effect will be, so if we start using that, I very much encourage that we should go and find out and then document some of the knowledge we gather into it's style and usage recommendations guidelines.
