To be fair, you both describe half of REST. Both interlinking *and* good cache/method behaviour (which most browsers don’t rely upon, precisely because WWW is not that RESTful) is required for a REST architecture.

It is also fair to say that most homegrown protocols do not benefit from hyperlinking, and weren’t made with REST in mind (and with vendor mime types) precisely because of that.
