Dear Miss Snark,
I've noticed a lot of agents indicate they're not interested in receiving queries for fantasy/science fiction, more so than any other genres. Why is that?
Hopefully this question is merely clueless, and not nitwitry...
Sorry, no clue cannon for you today. Your parting prize is the answer to your question. You may play in the Nitwit Stakes again next week.
SF/F has fewer publishers and a smaller market. Hard to make money doing it.
