Number of Tweets and Likes for any URL?

Hi,

I'm building a cool app that needs to check the number of "tweets", "shares" and "diggs" each URL in a feed has an then arrange them according to the number of "tweets" etc...

Any ideas on how this can be done? It shouldn't be that hard, but I cant figure it out =)

Checkout www.babblr.me , they have a similar solution. How did they do it?

Thanks!

• If you need to know the number of tweets take a look the tweet button.
