Url: http://klekr.com/editors_choice (should be near the top left corner)
Works in Safari, Firefox and IE.
I didn't do anything fancy from the Chrome's console log and dom inspection, addthis was loading the wrong url for a js file. It inserted the following element in head.
Of course then Chrome gave a 404 on the url used above.
Tested on Chrome Version 20.0.1132.57 on Mac
and Chrome Version 20.0.1132.57 on Windows
