I would recommend a reasonably modern single-page app for
<docs.schemers.org> since that address would be the obvious starting
point for newbies and many programmers expect something quite modern
nowadays. It gives a good first impression if we have something modern
there, in any case. Another reason is that the API will have a wide
variety of information. It will be hard to present all of it in an
interactive form unless we use a single-page app (there's just so much
of it).
