Notes Toward An Open Digital Bookcase

Note to all writers: The idea of an Open Digital Bookcase sounds intriguing. I don't know what one is, despite having read part of this article, but I think I'd like to know what one is.

But as far as I read, the article didn't tell me what one is, and more importantly, I found no hint or promise that the article would tell me.

As far as I read, they gave me neither, and I finally lost interest. If I had been confident that I'd be shown what an open digital bookcase is, I probably would have soldiered on, but lacking confidence I had to cut my losses.

So, please, when you write something long, give me some idea of the payoff, or even that there will be a payoff.

Thank you.

EDIT: style.
