1. Adding too many friends – as you probably already know Digg now undervalues the votes of any one who is on the submitter’s friends list. So the days of having 1,000 friends and getting a story to the front page within minutes are gone.

2. Using a boring title or description – this is even more important than it was before as Digg now places much more attention on getting random Diggs. The best way to convince users to Digg your article is with a title and description that not only catches their eyes but also encourages them to read the articles.

3. Only submitting content from one domain – this was bad with Digg before they made the new changes, but it is even worse now. You need to submit content from dozens of different domains if you want any of your submissions to get attention.

4. Not commenting on articles – now that having a huge friends list is a bad thing, the best way to get yourself noticed on Digg is by your activity. This includes making good submissions AND making frequent comments on articles.

5. Only Digging popular articles – to get your account attention you need to Digg articles when they are still deemed "upcoming." It’s also a good idea to comment on these articles because if it becomes popular your comment will be at the top.

6. Sending shouts for every submission – if you send shout outs for every submission you make then it will look like you are only using Digg to get traffic. You should try to submit regularly and only send shouts every once in a while.

7. Only submitting in "boring" categories – with the old Digg bloggers often suggest to submit an article to an obscure category as a way to get it more attention. The opposite is true now, you want to submit your content to popular articles so they can get as much exposure as possible.

8. Not adding any friends - even though Diggs from friends will not make an article popular, they still can get it listed prominently in the "upcoming" section. So having some friends is still important, but just don’t add too many. I would say it’s probably best to stay under 100 friends.
