Instability is supposed to be characteristic of electronic text: "Change is the rule in the computer, stability the exception, and it is the rule of change that makes the word processor so useful" (Bolter, p. 5). What rule is that? Assuming change isn't random, what rule or rules actually drive change? If the model is the process of electronic writing, using a word processor, to what extent is change driven by the internal structuring of the text itself. A computer makes this more feasible, but does it alter the principle on which one would change the text one writes? This is extended to the act of reading: "An electronic text permits the reader to share in the dynamic process of writing. The text is realized by the reader in the act of reading" (Bolter, pp. 5-6). Is change or "realization" any more likely in the context of electronic reading than on the printed page?
