A site like that could be useful if done well. It would probably be marketed towards parents and schools. Thing is, you would probably need to have a teaching certificate to be qualified to make a site like that at all. Not to say anyone will stop you from doing it, but most people wouldn t use it if they think you don t know what your talking about.
