As an aside, even though I had seen that Svbtle was a network some time ago, every time I come across a blog in its style I just assume it is some Wordpress theme. I sort of wish there was a better callout than at the bottom left to highlight everyone in the network.
I guess you could say Svbtle is sometimes too subtle. :)
I see the existence of the kudos button in this same light: random, transient visitors can either leave or they can offer a small token of respect and appreciation for the given Svbtle article.
You comment here is a perfect example of this.
I think the Kudos button is an interesting idea, but I'm not sure it's the right one. Something a little more malleable, something that facilitates a broader spectrum of opinion while maintaining simplicity would be better, I feel.
What do you think?
