Social media site Digg can be incredibly useful and entertaining. However it is important to remember that it is not MySpace or Facebook. Having tons of friends does not make you a superstar. More often than not Digg is increasingly becoming a marketing tool to push traffic to sites for SEO purposes. Part of the problem is blind diggers.
Users who digg articles without reading them simply because one of their ‘digg friends’ sent them a shout asking them to digg something. The value of a single digg is nothing, however harnessed a few hundred by an SEO company and you have front page material.
Don’t be a digg-whore! Be careful who you decide to friend. If you get a few dozen shouts every day. You might want to un-friend that user. Only you can keep digg unpolluted.
