I read the above as "all YA book you see on store shelves nowadays are cheap/lazy imitations of a select handful of bestsellers, and all of the covers look the same."
If I'm misinterpreting anything, I welcome your clarification.
All other things being equal in regard to marketing, yes, I believe that a book with the additional exposure of sitting on the fourth shelf from the bottom in a bookstore has more of a chance of being noticed than one you may only order POD copies of online.
Yes, you are misinterpreting my words, but I'm afraid that my clarification will make matters worse. I don't know what kind of books you write. There are many wonderfully educational and inspirational YA novels published by Scholastic, featuring well-rounded protagonists. And then there is "Gossip Girl". If you are the author of the "Gossip Girl" series, and you take offense to my distaste for it, so be it. I didn't realize I had to love all genres and all trends. But you cannot deny that the popularity of "Gossip Girl" was built on the popularity of "Sex & the City". You know what they say. If there's a Wendy's, there's a Burger King across the street.
Please, don't take offense. There are many people who hate Neo-Victorian literature. And yes, the market is crowded. And the titles that sell the most copies are not the ones that are most advanced in the artistic sense. This cannot be news to you. Undoubtedly, you've gotten good and bad reviews. I certainly have. All published authors have. Some people sneer at Neo-Victorianism in general.
