I guess I'm old fashion as I still like holding a book when reading it...but the times they are a changin'. E-books and services are convenient and generally cheaper and sure are becoming very popular. Will they have to stay with traditional guidelines or make their own rules?/ We'll see. If they are priced accordingly, I guess I wouldn't mind reading a shorter book, as long as I have some idea of its length. Personally, my stories always seem to fall into the novella range (45-60k) for some reason.
So I guess the market will probably rule as it usually does.
Good topic, Jeff.
