I've added a Digg This feature to slickhouse.com today! It will allow you to Digg any posts made by me, on slickhouse.com
If you're the first to Digg the post, then you will be asked to provide a brief summary and title for the article, prior to submitting it. If the post has already been Dugg then when you click on Digg It it'll add another Digg to the stack.
If you're confused then read How Digg Works.
You'll need to register in order to Digg, but it's a short process and very worthwhile - as you can start Digging straight away. Who knows, maybe in a few months you'll have reached Australia?
I've been using Digg for a few months now - and you can check out my profile on Digg here.
