Record activity when user shares node to Twitter, FB, Linkedin, etc

Hi,

Thank you for your wonderful module!

Is there perhaps a chance that the http://drupal.org/project/service_links be included as an activity?

Basically record the activity when a user shares/posts a node to FB, Twitter, Linkedin, etc

Examples can be seen at http://mashable.com = "user shared this node" some minutes ago

Would be absolutely stunning :)
