Rowling tells court she's stopped working - Yahoo! News:
"'This is very personal to me,' said Rowling, who wrote the first Potter book as a poverty-stricken single mother and is now estimated by The Sunday Times to be worth about $1 billion. 'I am an author -- 17-years of my work is being exploited here. This is not about money.' Rowling has said she plans to write her own Harry Potter encyclopedia, which would include material that did not make it into the novels, and donate the proceeds to charity."

Now for all intents and purposes, Ms. Rowling appears to be an intelligent and business-savvy woman. But she is missing the point here. Third-party products don't ruin the core product, they enhance it. They cause it to become essential. Yes you could say it "exploits" it but that's technical. Besides, this lexicon is based on a fan site. You do not want to alienate your fans. She needs to relax, take a week off in one of her dozens of posh homes all over the world, have a mojito or two and just chill out.
