The div created by the plug-in is no longer removed from the page if a badge is not going to be inserted. The DOM code for this may have broken a page in IE in some cases. This clean-up feature will be back in later versions, once the bug has been fixed.
The plug-in now only operates on single pages (posts and pages). The multiple requests on index pages were causing other Javascript functions (like Google Analytics) to hang and not load properly.
Tweaked the way the styling of the div to fix a bug in IE. It should now correctly float in both IE and Firefox.
