Pollen: the book is a program

At the core of Pollen is an argument:

First, that digital books should be the best books we’ve ever had. So far, they’re not even close.

Second, that because digital books are software, an author shouldn’t think of a book as merely data. The book is a program.

Third, that the way we make digital books better than their predecessors is by exploiting this programmability.

That’s what Pollen is for.
