I'd heard about the game before, and downloaded it tonight because I couldn't sleep. I've already met briefly with a couple others, and I hope to meet more when it isn't obscenely early in the morning! For me, at least.
So far I've been turned into both a squirrel and a bird just by drinking from a pond of some kind, and run into some friendly faces at the pond. It's been fun and relaxing, and overall nice - i'm hoping to nail the etiquette down soon, too.
So there you have it! Probably going to head off soon, though. I'm very tired.
