Have you heard of Digg? It’s a cool social news site where what’s on the front page is chosen by YOU. You can vote on stories with just a click of a button, and whichever stories and links get the most votes rises to the front page.

Digg is also known for the Digg Effect, which is namely that because Digg has a large audience they can easily drive thousands of visitors to your site in a very short time. Often the people you see at the top of blogs of the day are there because of a lot of external traffic from a social news site like Digg.

(On most normal websites the rush of traffic can cause problems, but on WordPress.com you’re 100% Digg-proof.)

Why are we telling you this? Because Digg has this cool feature where you can vote for an entry on Digg right from the page you’re on, assuming you’re registered and logged in. Putting this button on your posts can help drive a lot of votes.

To add this to your post, just put in [digg=http://digg.com/url_to/story_on_digg] and it’ll be transformed into a “Digg This” button. (Your story must already be submitted to Digg for this to work.) I’ve added a Digg This button to the right for this very post you’re reading, why not try voting on it to test things out?

A tip: try to only submit your best stuff to Digg, not every entry, that way you have a better chance of being voted up and not cluttering their system. Mark has written a step-by-step FAQ with screenshots if you need some help. There are no plans to add other news sites like Newsvine or such at this time, but thanks for your suggestions.
