Any link coming from facebook and other social networking sites is a good link. Google loves social bookmarking sites and if you e.g post a video at several SB sites with your URL in it and post the same video on your site and submit the page itself again to those SB sites you might get high google rankings but I advice you to pick up less competitive keywords to get high ranking by this method.
