I'm sorry for having to post this thread but I just can't find how bloggers are adding these links to their posts or RSS feeds. Can anybody help me or at least point me in the right direction? Cheers.

You will need to edit the php template that is used for your blog posts. Add some code that echos the current url into the format that submits to digg. http://ekstreme.com/seo/socialbookmarkingcode.php
There is a wordpress social bookmarking plugin called Sociable. You can read more about it at push.cx/sociable
