Obviously, I'm not one of "them." Entirely, anyway. My writing has appeared in several magazines for the adult market.
But, when considering my venture into the children's market, I straddle the fence on this issue–as apparently, do many other unpublished writers.
It shocked me at first when I ran into picture book or novel writers refusing to write or submit works to magazines, or take others' advice that their story is perfect for a particular magazine market. If someone wants to buy your writing, aren't you supposed to jump for joy?
