I like what your on to here @blueorgy, and it's strong to raise the topic about it.

I think there is one easy solution we could do, instead of complicating the rewards system, as @lukestokes point out. We could add an icon at the end of the header when someone doesn't vote on their own post, much like how we do when someone does a Power Up post.

This way we can signal early on that the post isn't a Self-Vote and should be encouraged to be voted on.

Of course, this mainly applies to the articles, not comments that are also a way to self vote. This is of course not a full solution to the problem, but one stop towards finding ways.
