Pluto's Endless Mysteries
First off, "The Plutonian Surge" is an excellent name from a story!
Secondly, It seems Pluto is mysterious even on the internet. I don't know what could have caused the surge, I can only offer guesses. The first photos of Pluto are still fresh; perhaps that has something to do with it. Or perhaps those photos spawned a mob of Pluto fans who've just discovered the site?
The Pluto-Charon system deserves more love, anyways. It's the only binary world system we've ever observed; that's got to be worth something!
