I too noticed the slowness brought by placing the widget on the main page. Like getxb I hosted the image and js. Still saw slowness due to their html page served offsite.
Just checked the stats of one site that gets ~10k page views a month. Two usages......buuuhhhbbbyyye! (Took it off). Added to 'to do' list of other sites weekly tasks.
