Well, that post of Rusch's that I linked to earlier has led to an enormous spate on on-line debates about the merits and shortcomings of Amazon's KDP Select exclusivity program. (Am I overly cheery? It's just that my immediate gut reaction to that post was "happy dance!" and other people's reaction was...NOT happy dance. Maybe it's just evidence that you'll be happier if you don't take everything personally.)
Passive Guy noted the discussion on his link to the post, so he made a special post for it. Worth a read if you want proof positive that EVERY BOOK IS DIFFERENT. Yeah, sorry about that--this is why stuff like this can be argued forever and ever. Some people make big sales on other retail sites, so exclusivity with Amazon would be a fiasco, while others do marvelously well with KDP Select. And just to complicate matters, still others have some books of theirs that do really well on other retailers and other books of theirs that do really well on KDP Select, or they had no sales on other retailers for a long time, but now all of a sudden, they're seeing sales. It's insane.
It's also something to keep very much in mind whenever someone offers up an easy-peasy one-size-fits-all process for marketing your book.
Anyway, the Rusch post did generate a lot of thought-provoking comments, as well as some of the other kind. (I'll just say that one of my least-favorite Internet fight tactics is to bluntly insult someone, and then to insist later that you never insulted anyone and that anyone who interprets your blunt insult as an insult is crazy and stupid, but somehow calling such people crazy and stupid isn't an insult, either. All of the troll tactics are low, but trying to gaslight people is really low.)
One comment that's a bit off the topic but still worth talking about was this one by someone worried about their financial situation. Rusch and some others have some really good, realistic advice--I mean, it does all kind of boil down to "get a job," but they are not the least bit douchey about it. I liked Camille LaGuire's metaphor about writing not being a financial life raft--that's what I mean when I talk about protecting your core income and diversifying your sources of income. Writing is great, freelancing is great, running your own small business is great, but secure and predictable? Oh, no, it is not that.
