Tread lightly. There seem to be dozens, hundreds of new philanthropic web services, and almost all of them have an incredibly difficult time of distinguishing themselves. My suggesting is to stay very narrow to one field. Better yet, join one of the others (Clojurerocks seems nice). You don't need your own charity business to be useful, especially when so many good ones already exist and are trying to innovate themselves.
