I hope all of you have a Stumbleupon account. If you have not heard of stumbleupon or does not have an account, you should read this post from my friend Derick.
Stumbleupon – The beauty of Sharing

From my own experience, stumbleupon gives you traffic, and that too in large numbers. Some of my posts get around 7K to 10K visits just from stumbleupon, and that too in a week.

When I started using stumbleupon, I had no stumble friends. None stumbled my posts other than me. Then I found a few friends, powerful stumblers. Id send them my post and they will stumble if they like my post. All my good posts with a global appeal gets lots of stumble traffic and the bad ones, or irrelevant ones are ignored.

Coming back to the stumble cult, its a private community of stumblers. Stumblers will get a list of member posts, and they can stumble the ones they like. Similarly, they also can submit their links for others to review and stumble. The cult is a place to get good seed stumbles for your posts.
