Neah, we just have different mentalities :) Don't you have more satisfaction when there are other people voting your posts instead of yourself?

And also, don't you find it more satisfying when you upvote a complete stranger, who worked a lot for a post that nobody upvoted?

On the other side, I don't judge anybody who self upvotes. This whole place is something completely amazing, because we can see how people act as communities or individuals when money are involved. And it is a case study that keeps the data immutable. I guess this should be more expensive than it really is :)
