It used to be taboo to promote your own blog articles on Digg but, since June 2010 when the social bookmarking site was improved, this is no longer frowned upon.
This change should be good news for you the blogger, for your goal is to increase inbound traffic and eyeballs, right?
Presuming you have an RSS feed for your blog, you merely have to log into your Digg account and follow the prompts to verify to Digg you are the owner of your blog.
In my case, I needed to include a gobbledygook series of letters and numbers in a blog article — eebfd1c39e0044b082ac752b5a2cce45 — which Digg discovered when this was syndicated through RSS.
Every blog has its own verification key.
Of the many benefits of Digg, what do you like and what do you hate? Are you an active Digger? Care to share any pointers below?
