GET the number of tweets, likes and diggs for any given URL?

Question

Hi,

I'm building a simple app that should count the number of tweets, shares/likes and diggs for any given URL.

The URL could point to a blogpost, news article, etc.

I know that Facebook has this FQL command to retrieve the amount of likes for any given URL:

SELECT like_count FROM link_stat WHERE url="any url...";

Thanks!
