Advertising to The Non-Kindle World

I don't know if all y'all realize that Dying Embers is now available pretty much everywhere* books are sold online.  Using Draft2Digital, the electronic version has been uploaded to all the big, non-Amazon names, as well as a few I've never heard of:

Barnes & Noble
Kobo
Apple

Page Foundry (Inktera)
Tolino
Oyster

Which is all well and good.  I like everyone to be able to snag a copy of my book if they so choose.

The problem, of course, is letting everyone know they can now get Dying Embers through whatever outlet they choose to use.  I mean, I can put it here and on FB, and tweet about it.  But that only reaches those people who already know about me. :waves:

So, I went searching for ways to advertise to those other markets.  When I go looking for ways to advertise to Kindle users, Google is chock-full of places.  The others?  Not so much. 

Oh, I can get some non-Amazon advertising piggybacked on those sites geared for Kindle people.  Some of them allow for links to other vendors.  But since the site is focused on Kindle readers, not a lot of others head over there to look for books.  The plethora of book sites for other devices just isn't there.

Amazon holds about 60% of the ebook market (depending on where you're getting your numbers) and it's not hard to see why based on this search I've been doing.  There's just more ways for people to find your books when you're published through Kindle.  Which is kind of sad.  Of course, Amazon also makes it way easier to actually publish a book, make your book visible, get you sales data...  But that's a post for another day.  Perhaps if B&N tried some of the things that make Amazon so popular, they'd have a bigger marketshare and more books would be published through them.  :shrug:

So, anyway, I'm still looking.  If I find anything, I'll let y'all know.

Now it's your turn.  Do you have some other device besides Kindle that you read books on?  How do you find new books?  And if you're a Kindle user, what's your go-to place to find new books?

*I recently chose to delist the book from Scribd. Not really keen on some of the things I've heard about them. I hadn't gained any sales from them anyway, so no measurable loss on my part. If you're a Scribd subscriber, I apologize for any inconvenience.
