On his site, Daniel Pinkwater shared that his twitter-pation of tweets was him writing the prologue of his new book directly to Twitter:
What I posted on @danielpinkwater was written as I went along. I have some things in mind for the rest of the book. I’d prefer it to be published as a conventional book, and there is some chance that may happen–in that case I’d rewrite the prologue in a less twitteroid manner. If it is not to be published in book form I might twitter more of it, even further modified to work as tweets.
Let’s hope a publisher picks up the rest of the book! Meanwhile, the tweeted prologue is collected here.
In other Pinkwater news, he is publishing a lot of his past books in e-book form.
