AddThis the Social Bookmarking service have added a really neat feature that shows you the most popular services users share to using the AddThis widget.

The data is useful because it will allow you to fine tune your first 10 share options on your addthis button or addthis bar, not much point in offering a share service up front that users in your country have little interest in.

I have grabbed a screenshot below of the USA to UK Shares, very interesting with Twitter in 5th in the USA but 3rd in the UK of course Facebook is top in both but even so it shows the UK has a real love for Twitter over the more old school Print & Email to friend.
