Freedom for the author is obvious . If I want to take my argument in different directions, I can create separate Web documents and link to the parts I wish to include. For example, in a print version of this work, I wouldn't talk about how few people find theory useful because I have a duty to stick to the argument. However, since this is hypertext I can create another node and link to it. As Gregory Ulmer puts it, my job here is to construct possibilities for readers.
Authors also have freedom to choose the means by which to present information.
