I feel really sorry for JKR, having her anonymity busted in this way. I am glad that for a while though she managed to see a truer reaction to her writing, and enjoy publishing without the hype. I'm sure she's fine with it all and expected it to come out at some point, but still, that was my first reaction. I don't get this rush to read her other books - they're not HP books and should be judged on their own merits. So yes, I can entirely see why she did this and I'm pleased for her that she got positive reviews before this story broke. How soul-destroying it must be for a writer never to know if anyone actually thinks your writing is any good, because they will read anything you write, regardless of merit.
