First, Stephen King. This gets a big shiny gold star from me for how he says teaching can be like a brain suck. Also: he threw away Carrie. I'm sure you've heard the story before, but it's still cool.
I found these questions that you should ask a copy editor before hiring him quite intriguing. It also confirmed that, although I am a self-professed grammar queen, I am perhaps not suitable to be employed as a copy editor. I certainly don't have a favorite dictionary.
Book sales. They suck. Except for, yanno, kid lit. Which kinda rocks for me and everyone else writing kid lit. But I liked this article because it filled me with spiteful glee (as, personally, I think it would be better for publishers to invest more cash in debut authors than slapping down too many bills for a sophomore novel):
Other big titles showed mixed results. “Her Fearful Symmetry,” the second novel by Ms. Niffenegger, author of the best-selling “Time Traveler’s Wife,” sold just 23,000 copies in its first week, according to BookScan. Publishing insiders suggested that was a disappointment given that Scribner, the unit of Simon & Schuster that published the book, paid Ms. Niffenegger close to $5 million for it.
Lastly: I won this in a Twitter contest. How cool is that? Will update you all on it's usefulness, if you'd like.
