It's great to learn new things! A while back I tried to integrate Digg buttons into my individual posts. I had given it up as a lost cause when I decided I'd try one more thing, and voila! It worked! (You might have seen the Digg buttons popping up here and there on my blog.)
You, too, can promote your work using buttons from the Digg Integration Tools page on Digg. It's a little tricky (at least for me; remember, I'm a writer, not a techie!) but if you have any questions, feel free to comment or email me.
Digging your blog post is a great way to get a boost in traffic. Just keep in mind that the Digg audience can be a little opinionated at times, and be prepared to receive some varied feedback. To supercharge this technique, build up a list of friends on Digg who you can share your link with once you've dugg your post.
