Understanding social news communities and how they work is paramount to defining the meaning life. You’re not going to nail it because it’s an evolving answer. But, like the meaning of life (i.e. religion, philosophy, Pink Floyd, etc.) there are always going to be folks trying to frame social news communities, behavior and success.

Dan Zarrella is a digital colleague I’ve come to know by participating on social news sites. He is one such person who is adding to the social media world today with an interesting report and some nifty little tools to better understand social news submissions on Digg.com. Dan’s report, entitled, “Link Attraction Factors” (click title for a PDF download) looks at articles that made the front page of Digg and which produced the most inbound links as a result.
