For what it's worth, the game isn't on IJ or tumblr. It's a small-scale game so we've decided to host it on LJ, which is where it was hosted even when IJ hit its highest point (and most prospective players are more familiar with it, etc.)
Would gdocs work well with real time games? We're trying to use something that most people will have access to and which will work for scening in real time (scenes via e-mail are still possible if people need it).
