Sorry, this does not excite me. It reminds me of the B&N "Local Writers" display. If you can't get a book signing at B&N because your book is POD, they bring together 15 -20 local POD authors to sell their books on consignment in the B&N store.
That positioning says, "less than."
If PW said they had a team of readers who would vet the POD & self-published books for quality and then incorporate them in the mainsream of traditional published books for reviews, etc., then I would be excited.
Their supplement is like going to the Publish America bookstore....everything from great to awful with no way of knowing. Same thing with Kindle and Smashwords. Fictionwise requires books be submitted by publishers - at least that assumes a book has been vetted.
First Chapters Plus, a new ezine by Reader Views will take any book and advertise it for a fee. It tends to have a lot of small press and POD, but I ran an ad; it's totally democratic. It gets lots of google action and action from online bookstores looking for an excerpt and synopsis. The reader of the ezine gets a first chapter to review and decide for themselves if they wish to purchase the book.
