I love the kudos feature. I've used it so often, especially on shorter fics. For things like drabbles and flashfics, there's rarely more that I can say in a comment except "Nice, thanks". The kudos feature lets me do that without having to think of a unique way to say it for the hundredth time. I've found myself reading more short works now that I feel like I can leave a response without having to come up with words. (Or, on the writing side, that I can get a response without having to come up with words. There's only so many ways I can say "glad you enjoyed" without it looking like a cut/paste job.)
