Jason Fried previews the next product from 37signals on Twitter X, called Workbook:

It’s a dead simple platform to publish web-based books. They have covers, they can have title pages, they can have picture pages, and they can have text pages. Each book gets its own URL, and navigating and keeping track of your progress is all built right in.

Intrigued by this. We can always use more ways to easily publish to the web.
