There are a lot of niche social bookmarking websites, and if you dominate these with your own posts, you can drive insane amounts of traffic.
So how do you use these small(ish) websites to your advantage? First, you'll need to find some friends. Four or five should work.
Next, create an account for yourself, your blog, and have your friends create accounts. Then begin bumping up interesting articles the community supports.
Submit your own articles once they're published, have your friends bump them up, and bump it yourself with your blog's account, and you can easily start to dominate the "popular" page of most pligg sites.
A little dishonest, perhaps. But it totally works.
