There’s a trick which FB is doing in the code samples and can be important if you are on https:

e.src = document.location.protocol + ‘//connect.facebook.net/en_US/all.js’;

Essentially making sure that the protocol is matching the current URL’s.

Manual, I checked out your js. Does it require that you clean up the script first, e.g. I see in your example html that you have hardcoded some script code in the, including manually breaking up the tags etc. Doesn’t your script automatically prepare the remote code?

This will work only as long as the remote scripts do not use document.write to output HTML content to the current page position. Using document.write after the body is loaded will clear the current page content,

If you need to execute arbitrary JavaScript code delayed at the end of the page, you need to use better tricks. That is what the Fast Page Content Loader component does.

And noone remembers, that script tags already support asyncronus loading on pageload. At least in some browsers.
