Can Digging your Own Article Get You Penalized?

That’s the million dollar question. What happens if you Digg your own article? According to Digg, you are free to submit your own articles. But in general, it’s a good idea to your readers submit your articles to Digg. Now I did submit my article to Digg a couple of months ago and in 3 days my site was completely dropped from Google. I am by no means suggesting that had anything to do with my ranking drop, but it’s interesting that it has happened to a bunch of other people as well. What’s your experience with Digg? Have you experienced such an issue?
