Thousands of what, you ask? Thousands of TweetBookz.

That’s right. It’s exactly what it sounds like.

From the about page:

Our concept for TweetBookz is to bring content as short-lengthed and short-lived as tweets to the “serious” world of books.

($30 a hardcover and $20 a paperback)

The FAQ page is even better:

Is there a minimum number of tweets I need to have? How small can the books be?

You need at least one tweet that we can print and books are printed with a minimum of 20 pages (holding 40 tweets). If you have fewer than 40 tweets we will fill in the rest with nicely designed blank pages.
