There’s been a rush in the last year to get as many ebooks out as possible and the quality shows. Surveys show readers’s attitudes towards this. The overwhelming point respondents demanded in the survey was quality, even above cost of the ebooks.
When a market first develops, the early adopters are willing to forgive things because they’re the techies and they know this is new, but as the market broadens the people who usually read print books are not going to accept this.
The public will punish those ebook publishers buy simply not buying their titles. I’ve seen articles about people returning ebooks because of the errors in formatting, and you see blog comments and reviews on books that mention these mistakes. I’ve heard authors talk about a particular “publisher” (how he calls himself, also he is none) they were using due to very low cost, but the errors made them rethink it. The market will dictate the readers’ demands for error-free reading.
