Are Nook Readers Hopeless Romantics?

Recently on a self-publishing forum that I frequent, a much more successful indie author than I asked the forum if we had seen our Nook sales dry up. I was one of the few people who answered "No". In fact, I have had a couple of months in the latter half of 2012 where Nook sales were all I had.  This prompted me to look a little closer at the difference between my Nook and Kindle sales and what some of the differences were. First, let's review the ebooks that I have and the differences between them (in case you haven't read them yet). I'll try not to give any spoilers.

With that said, it's interesting to note that 84% of my Kindle sales are of The White House. This isn't completely surprising in since The White House was released four months before A Fond Kiss. However, 100% of my Nook sales are for A Fond Kiss. That's right, I have not sold a single copy of The White House on the Nook. Which is a shame, because it's a really good story (not that I'm biased or anything;)

This is what leads me to ask the question at the top of this post. Are Nook readers hopeless romantics? It's pretty clear that my based-in-fact love story appeals to them far more than pirates, even famous ones. Is it because A Fond Kiss is a love story, or because it's based on a true story? This of course has me wondering what's different about Nook readers vs. Kindle readers.

After a little frustrated searching online the only information that I found about the demographic differences between Kindle and Nook readers is a couple of years old. Since the e-reader market has exploded in the last couple of years, I'm not sure how accurate that information is.  This article from ireaderreview.com shows that Kindle users tend to be older than Nook users and credits the Nook color/tablet with attracting a younger audience. It also suggests that the older audience prefers the Kindle because it's lighter and therefore easier on arthritic hands (A dubious conclusion).  Given that this data is from 2010, before the Kindle Fire was released and was from a self-selected survey, the data isn't exactly that scientific. In fact, based on my experiences both as a reader and author, I found the idea that the Nook appeals to a YOUNGER audience surprising.

Here is another article from the Florida Research Group that compares the demographics of all e-reader users, but again it's two years old. There is no end to the number of articles comparing the devices themselves, and they're great for consumers shopping for a device, but there really seems to be a limited amount of market research done for authors looking to maximize their sales on either one. If I were about to publish a romance novel and was trying to decide whether or not to opt in to KDP Select with its exclusivity requirement, I might like to know a breakdown on Romance genre sales on Nook vs. Kindle. Otherwise, I might lose sales from other platforms that have a large number of readers in my genre. For independent authors running their own show when it comes to marketing, this kind of information would be very helpful in targeting that marketing rather than the current throw everything against the social media wall and hope something sticks strategy or the increasing popular mimic the best-sellers (50 Shades of Fill-in-the-blank) and ride the wave of whatever's popular strategy.

Maybe this is something that KDP, Pubit and Smashwords can offer as a value add to their authors. Maybe it could be another revenue stream for them. I can imagine that I'm not the only author who would pay a REASONABLE  fee for a timely demographic analysis of e-reader users or even monthly newsletter that goes beyond just the bestseller lists and looks at who is buying. I would think that this is all data that these e-publishing platforms have, it would just be a matter of putting it together in a form that people can read.

Admittedly, I'm new at this and I've been eyes deep in editing lately, but this doesn't seem too much to ask. Maybe this is out there already. If it is, please point me in the right direction. I'm sure it's a product of my corporate sales background, but I can get kinda nerdy about this stuff, and as the saying goes, Knowledge is Power.
