Any plans for public[-ish] user profiles? Or a message board / daily comments thread?
Also, not sure if you have any desire to branch out, but this game is one I've played from time to time on one of those new-reddit integrated game things they have, and it's great to have a place to do it that's not reddit. There's another game there that I would nominate if you have any such interest:
You start on a Scrabble board populated with two words, and you have to build a connection between them with the tiles you're given (a persistent/common set, I believe, that replenishes as needed, also with the same letters in the same order for everyone). The surface objective is to do it fast (I want to say you get a minute but I'd have to check later to be sure), but there are other ways to approach it. I like to iterate toward a maximized score in the time allotted (in the reddit-games implementation, you can exit and restart without penalty, and you can make plays that aren't directly productive in the sense of connecting with the other pre-populated word; play ends once the connection is made).
