There's a compnay that makes really cute purses but everytime I buy one, within a month I'm sewing it back together. This has happened with several different styles so it's company wide poor workmanship. Mo matter how cute, I just can't buy that brand anymore. Their quality has killed my brand loyalty.
As a writer, you are your brand. No author will please eveyrone but you need to make sure you don't alienate your readers by sloppy or lazy writing. Or they'll stop buying your brand.
