There's a lot of thought that's gone into the design of JFBConnect for both browser and Facebook compatibility. The code needs to load in the body of the document because it's specially setup in a way to 'defer' the loading of the Javascript until after the full page has loaded. This allows for a faster load time (in the head section, the Facebook library would have to load fully before the page is loaded) while also allowing for the Facebook widgets (Likes, Comments, etc) to be guaranteed to be displayed on the page to the user.
What we do is recommended by Facebook, and has been only slightly modified by us for some compatibility issues that we've run into to make sure everything goes as smooth as it can.
