One aspect of WebFonts is that we can have web fonts for special interest groups; there are fonts that are optimal for people with poor vision. The same technology that enhances the accessibility of our website for mobile phones can also be used in this way.
The availability of WebFonts can make a difference in the thinking about a new framework for skins. When accessibility is taken into consideration, the colours and the font used determine to what extend a Wiki can be read.
Accessibility to our content is served by WebFonts. The application is not restricted to those scripts where we cannot expect an appropriate font to be available. For the English Wikipedia WebFonts will bring accessibility to the visually impaired.
All this is in our future and, the first step towards this future starts with the code review of r85549.
