If you are a blogger you should be on Digg. Its not a question of usefulness, its fact. Of course I'm going to sound a little hypocritical here because I don't have a Digg button on my blog (but we are working on it). Anyhow, you should. Digg is to blogging what YouTube is to video, its the tool to take you viral. All you need is a few readers to Digg you and it can start a mass trend that will increase your visibility.

If you don't know what Digg is, here's how it works. Digg is a social bookmarking tool. People create profiles then digg blogs and articles they enjoyed. They have a friend network who can then read things they've dugg and decide to digg then as well. Then those diggs are posted on their profile and so and so one. Diggs that are in the couple hundred end up on Digg's first page. And lots of people read those. Digg also allows for comments and discussion about submissions. Right now I manually submit every post I write and digg lots of others. Its a great way to promote people who you read and subscribe to as well.

There are lots of sites out there about how to use Digg for SEO, here is a review I like at imediaconnection.com.

Its not hard to download a widget that you can put at the bottom of your blog. Then your readers can easily click and add you. Trust me, I digg far more often when there is a link. Most humans are simple creatures with short attention spans, they need a little easy reminder if they are going to digg your article.

Also find your friends on digg. If you are already using other social media post that you want to add people. Of course let me remind you of my soap box: the Golden Rule. Read and digg other people. This does not mean just digg whatever your friends post. Take some time to read articles and give feedback. Digg it forward and create your online word of net trend!

Digg what Veribatim thinks is hot here.
