Do people post their own stories/blogs... or is it more common to get someone else to find it and then digg it?

I don't think it's uncommon to digg (or reddit) your own stories. Sketchy if you're all about being super ethical, but that's about the only drawback. I don't check out digg too often, but I read somewhere they had some problems with people spamming it with links and bumping spam up the charts.

never heard of reddit... neat
