This being my second post in a row about blogging, I may be in danger of excessive self-referentiality. (But then isn't even one act of self-referentiality excessive? So if you're going to do it, do it big!) In any case (a convenient phrase of dismissal) I am going to risk overstepping my rhetorical bounds because I think the blogging medium offers a great format for developing ideas. If I were still teaching writing, I would definitely make it an assignment for my students to blog daily. Since blogging is writing for publication (I do believe more people read my blog than have read some of the books I have published!), and nothing improves your writing faster than knowing that people are reading it, it would be a wonderful teaching aid.
My current plan is to write a book on the physics, philosophy, and psychology of time. And based on my experience in blogging, I have decided to structure it in bloglike units. It will have chapters and so on, but the real unit within the chapter will be something that is more or less self-contained, like an individual blog entry. Not only will this make it possible to read the book non-sequentially, it will induce all sorts of thematic cross-referencing (without the hyperlinks, of course, at least in the non-digital version). In the process of writing I will be posting entries on the subject of time, thus generating content in a form that may eventually be reproduced in the same form in which it was written (or more likely go through a lot of transmutation first, perhaps to end up in the bloglike state from which it began). It will be an interesting experiment.
