It always amazes me the diversity in those who write!
I taught a seminar last night on publishing at a local NC college and the range of people was quite amazing. Not so much the people themselves, but the goals and ambitions they had for their work! Every person came from a different background of writing and had their own style and preferred genre. Their tastes in what they read for pleasure were diversified as well.
Guess that's why book stores carry so many types of books!
