Just because something isn't special to you doesn't mean it isn't special to someone else. I would argue that special/not special often makes the difference between an author who has rabid fans who want to read their books specifically, and an author who writes books that are basically considered fungible with any other similar books that the reader can find in KU.I respectfully disagree. "Good enough" fuels just about every full-time author's career. There is no "special". That's something writers mention as a means to explaining any given author's success. It's a false notion at best, and gatekeeping at worst. Agents and publishers dine out on the idea of talent and special.
In the end it's about packaging, marketing, and being entertaining enough to hold interest and get someone to read the next one. It doesn't take special-ness to achieve that, and really that limiting belief is what keeps the non-fiction "How to Write" industry flush, and stops a lot of people from even trying.
What's real and what's apparent is that bad writing is rampant. What makes so many badly written books bestsellers, however, is slick packaging and that they're deemed 'not boring' enough to enough readers.
Also, something being special isn't a false notion. Not all things are created equal.
