The main reason that publishers turned down my book proposal last year was that they considered my audience to be limited. They didn't think there were enough introverted Christians out there would be interested enough to read it. Even now, I'm getting the sense that people do not expect my book to sell all that well. Personally I do not agree. If my book has good content I think we could generate a lot of interest.
It all comes down to marketing. It occurs to me that marketing to introverts might be aided by creative approaches. Introverts utilize technology and read quite a bit. What do you think? What are your ideas for marketing to our demographic?
