Mystery string being appended to URLs

[cineweekly.com]

I can't find the source of a string of characters that is being appended to the end of my URLs. The string changes every time I refresh the page and the only page it doesn't show on is the homepage:

#.TlKtumt5duo
#.TlKvQWt5duo

Things I suspect are Google Analytics, Google+1, Facebook "Like" button, IntenseDebate comments (even though it shows when not logged in and on pages without commenting), and an Amazon Affiliates link widget that uses Javascript to automatically convert links to affiliate links.

Disable each one of those things and see if it happens, then you'll know if it's them

Haha, thought of that and attempted for a while but it got too arduous. I'm also suspecting it's a combination of things which this method wouldn't help. Just thought someone else with those widgets/plugins recognized it.
