As I was searching the internet for new social media sites, I came across this article: http://www.onlinebusinesswatch.com/online-business-from-home/using-digg-for-business-marketing.html 

Digg.com is another social media site that can help businesses with their marketing strategies.  There are so many people on social media sites every day that having a social presence on those sites can increase awareness of a business’s products and services.  At Digg users can create profiles and post their ‘diggs’ (bookmarked links to other sites) for other users to see.  Digg can help companies gain traffic to their business’s website through the popularity of their posts, which can be tailored to meet advertising needs.  By ‘digging’ companies can uncover new found exposure to new potential customers and gain a social presence on the internet.
