We created a script of our own that did this for the share buttons on http://viralsweep.com/advanced-sweepstakes-guide http://viralsweep.com/advanced-sweepstakes-guide and the main issue we had was that, depending on the service, you may have to specify whether it's www. or whether there is or is not a / at the end of the URL. Services like Sharetally are neat because they do the crawling for you, but the numbers still may not be entire accurate; especially if you consider URL shorteners and how various services crawl and report those. Even more confusing is why some services (in particular, g+) seem to over-report the number of shares, only to self-correct later on (by as many as 10-11).
