Write, or buy a lottery ticket?

In a Guardian article on POD (publish on demand) books, we find this charming side dish:

. . . 50% of all published books with an ISBN (International Standard Book Number) tag sell fewer than 250 copies and barely more than 1% of manuscripts submitted ever get published.

Interesting numbers; I don’t doubt they are true. Yeah, the odds are stacked against us.

What I don’t understand is how POD is supposed to help. Sure, by publishing yourself, you are, technically, um, “published.” But does anyone think that by self-publishing, you can improve your chances of selling more than 250 copies? Even if Amazon does list your book?

Sure, you bypass the multiple gateways of agents, editors, publishers, distributors, and booksellers. But not the readers. Ah, the readers . . .
