I have KU. If I didn't want to read indies in the program, I wouldn't have to. There actually are 1000's and 1000's of publisher books in the program. And I also enjoy the heck out of a lot of the amazon imprints books. They got some big names in one of the imprints I like reading. They also have bought up a couple of publishers which meant back list titles.
And there are a selected group of indies that are in the program that are excellent. Of course, I don't go randomly browsing in there, can't find anything that way. I just keep adding stuff to a wishlist I can access from my kindle. I been nursing that wishlist for a while so it has a lot of recommendations on it. Over 300, which would keep me busy for a while.
For big publishers I use their sales and the library.
Interesting is the tidbit, assuming its not just hogwash, about them trying to get 50 shades.
I read 50 shades in October 2011. I borrowed it from someone through the kindle borrow system. At the time the book was not with a big publisher yet, but the smaller one that initially had it (The Writers Coffee Shop), which is why it was borrow-able still. In November 2011 Amazon announced their first imprint Montlake for romances. So I guess the time like rings true if they did actually try to get that book. They ended up launching Montlake with Connie Brockway, great author, big name in the genre.
But to say that its just garbage in KU is just not true. At least not anymore. Now I did cancel KU the first time when all the short porn pamphlets flooded in because of the silly payout. But once they changed that, lots more novels came in and its been a lot of fun. But again, one cannot normally browse, at least in the genres I read as its full of a lot of scammers right now in romance stuffing the titles and keywords and putting up garbled garbage.
I just check recommended books on goodreads and it tells me there right away if its in KU, if it is, goes on the wishlist.
Hey, I got KU for 5.99 a month for 2 years in July so I find enough a month to make it worth while. I read more books a month anyway than just KU books so there is that.
