 * From the outside, the plugin “does what is says on the tin”: a FaceBook like 
   button is added to the (top,bottom) of every post and page.
 * However, the technical implementation is not good: in multiple-post pages, each
   Like button is added as a new instance of the FaceBook API script, which causes
   multiple inits of that script (one for each button), which in turn causes large
   loading times and unnecessary overhead.
 * More importantly, if users have turned off cross-domain scripting, which is a
   browser security feature that is becoming default in most modern browsers, the
   button’s code causes an error “Blocked a frame with origin Facebook.com from 
   accessing a frame with origin <your site> – protocols, domains and ports must
   match. This causes the button load to fail completing, upon which the button 
   re-initialises. This cascade of errors takes up full CPU and render your website
   unworkable.
