Until five minutes ago, I hadn't pondered the question. But now, I'm convinced that it is one of the most useful questions a newly-published writer can ask themselves.
As a journalist who has interviewed countless writers, I love it when a writer and I understand each other going into the interview. This bit of wisdom from Publicity Hound is priceless:
"If you don’t know the reporter personally, Google their name and see what you find. If the reporter blogs, read the blog!"
