I think it's a good first shot. I'm wondering what's going to happen to a completely anonymous forum as it grows. Will it devolved into /b-like behavior or will it find a way to rise above.
I'm hoping that the theme, some new features, and me keeping an eye on spammy content will make it rise above. I'm wondering just as much as you, though!
I am having fun with it, and it doesn't seem to be devolving.
Side note: I really want an iPad version. The interface doesn't even need to change at all, with the possible exception of making the airplanes a little bigger. I run it in 2x mode, but font rendering is massively ugly.
