Totally agree, I think the Kudos system implemented in Svbtle and other clones is fundamentally broken until there's a way to undo it. Just hovering and waiting in place for a trivial action is a pain (and many people toggle with it accidentally thinking it's some whimsical animation), no less that being at the top of the page is completely backwards in itself; put it at the bottom after I've already read the post enough to judge it.
