Is Digg a harbinger in social media?

Techi: Digg isn’t the first social media site to fall. MySpace collapsed under their own weight. Other social news sites like Propeller, Yahoo Buzz, and Mixx never got the traction they needed. Facebook pushed out a lot of would-be social networks over the years. When Betaworks bought Digg for a ridiculously-low amount, it didn’t mark the first failure of a social media giant.
