The word "snark" anecdotally has picked up steam in public discourse. Keith Law calls himself a "deliverer of snark." One of my favorite twitter feeds is SnarkyJesus. Keith and SnarkyJesus have a following because of their snarkacious abilities.
I have to admit, I like the word snarky. I'm not sure I like snarky as a general posture or attitude. I like how Keith Law tends to use it for instances when he receives a statement that has little or no thought behind it. I'm not sure snark inspires growth in the snarkee, but in this newly expanded idea of "all the world's indeed a stage (imagining Geddy Lee rockin' out to one of my favorite songs of all time, Limelight)," I enjoy watching someone get snarked. If I receive snark, it needs a foundation in thought to be enjoyable.
Hard to tell what the shelf life of this word will be. Time to go read some Keith Law for my Recommended Daily Allowance of snark today.
