This is the seventh in an ongoing series called “Beyond The Big Three,” which highlights social networking sites other than Facebook, Twitter and LinkedIn. There are tons of other social media outposts on the Web, and they’re great places for associations to curate content. The first five installments can be found here. Stay tuned.

You may have heard of Digg before now – it’s a pretty popular link-sharing tool. In its own words, Digg is a place for people to discover and share content from anywhere on the Web.

Everyone in the community submits news articles, videos, images or blog posts to share. Once the items are listed in Digg, other users can vote on them – and when an item receives enough votes (called “Diggs”), it’s placed on the front page for all visitors to see. Even if an item never makes to the front page (most don’t!), they can still be discovered easily because each item has be submitted under a “topic.”

Digg is a great way to jump into social networking without devoting your entire marketing or PR strategy to the social Web. It’s also a great example of how crowdsourcing can weed out the spam (users can “bury” items) and the most popular items can rise to the top.

Digg is also aggressive (in a good way) about promoting conversation and allowing users to discuss the topics they’re passionate about. One of the great things about the site is that you can build a network of your friends, who can track what you’re Digging – and you can see what they Digg, too.

If you’re not into Delicious, Digg is a great alternative for sharing news and links that pertain to your membership’s industry or even association management in general. Because Digg has a broad focus, it’s also useful for finding interesting news stories and other cool things that you may not have been exposed to otherwise.

From what I observed through a few searches, the association management community isn’t too terribly active on Digg. But there’s no reason why your office couldn’t use it, even if it’s just for internal purposes. If you have a Facebook account, there’s no need to even create a new account for Digg – it lets you connect with your Facebook information and will automatically find your Facebook friends who use Digg!
