Being as this app was created by a blind person for blind people, it more than likely is not going to have too many sided people unless blind people invite them. But who knows, somebody might run across it in the App Store and snatch it up. If we start promoting it publicly, cited people will get on it. But there are no video components, so it probably won't hold their attention for very long anyway.
