Working toward a theory of links in regard to Ethos is working toward a theory of implication: What is the hypertext author implying, allowing, suggesting, and conveying through his or her placement of links? Because the primary defining quality of hypertext is the automatic, computerized movement from one linked node of information to another (McKnight 2) that it allows, I believe that careful analysis of the functions of links will yield the defining traits of a hypertext ethos.

The links' functions are the events with which HTML programming allows an author to surround the computerized "move" from node to node. Clearly the "movement" from one node to another is a defining quality, but the information is provided in the context of the links within the nodes. Links are capable of presenting information to the user as he or she engages them. That is, the reader will point the mouse at the link--at this point, the link can be programmed to react by placing information in the status bar or on the screen or in an alert box; the link form can change from functioning in a symbolic way to functioning in an iconic way, or vice versa. I choose to define the functions through consideration of Charles Peirce's theory of the sign. Using Peirce's "icon," "index," and "symbol," as funtions possible in hypertext links, I consider links as ethical or ethos building aspects of the hypertext medium. In all, the links allow functions with which the author can provide the reader material that will aid that reader in making informed choices about navigating the site.

I realize that not every website is designed for clarity, efficiency, or even "honesty." My theory of defining links by their functions is not one that suggests one must use these functions reader orientation; in fact, knowing the links functionally can aid one in subverting or playing with one's readers. Websites, like most rhetorical activities, are designed in many ways and for many purposes. So while many of my points in this hypertext sound as if I am promoting some single, necessary standard for linking, I am more or less ignoring, though not ignorant of, functional uses which are antithetic to the "facilitating" ethos possible for web authors. In my own web designs, I have attempted (and gotten better at) a practice of linking that embodies my "functional theory."
