Nice idea!
Some of your icons aren't showing up for me on Firefox, as FontAwesome is being loaded from a different domain without CORS enabled:
  Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote 
  resource at
  http://support.hirerefugees.org/plugins/font-awesome/font/fontawesome-webfont.woff?v=3.2.1. 
  This can be fixed by moving the resource to the same domain or enabling CORS. 
  downloadable font: download failed (font-family: "FontAwesome" style:normal 
  weight:normal stretch:normal src index:1): bad URI or cross-site access not 
  allowed
  source: http://support.hirerefugees.org/plugins/font-awesome/font/fontawesome-webfont.woff?v=3.2.1 font-awesome.css

There's a ticket for this on GitHub that describes how to fix the problem: <a href="https://github.com/cdnjs/cdnjs/issues/755" >
