A colleague and I were talking yesterday about how Internet reading differs from traditional reading. Obviously, it's less linear, which is why large chunks of prose seem less suited to Internet posting than snippets that get to the point. But also, when reading online, you're likely to click on a link, and maybe click on another from the site you've linked to. You may click on an audio clip. Or a video clip. It may be some time before you get back to where you started -- if, in fact, you do get back. Then there's e-mail.
All of which got me to wondering when this is going to be exploited fictionally. E-mail plays an important part in Peter Straub's most recent novel, In the Night Room, but where's the epistolary novel in the form of e-mail. Epistolary novels were all the rage in the 18th-century, when lots of people wrote lots of letters. Well, lots of people are writing e-mail. Most of it may be inconsequential, but a good fiction writer could surely do something with the form.
And what about a narrative using online techniques -- links and clips that lead the reader along the narrative path? Maybe published as a CD.
