I don't know too much about programming, but I am curious about this: Is it possible to make a 4chan (or any *chan) site, however simple it may be, in fortran? I seriously doubt it, but hey, that's what I asked for.
Well if you can write CGI programs in FORTRAN. I think you can, but I'm not sure. FORTRAN has modern filesystem access routines, right? So images and such could be done. Perhaps even an interface to a SQL database.
But it'd be like kicking dead whales down the beach.
