There’s no doubt that digg can provide an emourmous boost to your traffic. It’s great for ‘new’ articles and blog posts to give them a big rush of initial popularity. But it’s also useful for older articles - if you can keep the digg count ticking over, then you might have a shot at some of the long-term popular lists.

So, with this in mind, I wrote an article on how to display digg counts (like in the image above). It goes into some detail about how to retrieve the counts in PHP and via AJAX. And there’s full source-code as ever.
