UPDATE: Author and HP friend John Granger has written an excellent post at his Hogwarts Professor blog. Please take the time to read it all. It's excellent! You can find it here.
Commenting continues at the post "Trust, but verify" and it's now rolled off the page so thought we would put a link up here in case you are following the conversation on that post. Check Dee Dee's recent comment as well. She brings up some very good points.
Also, here's the more recent post on the recent opinions of author J.K. Rowling here.
In addition, you may want to check out these conversation threads on the topic. Our good friends at "Sword of Gryffindor" and at Hogwarts Professor are hosting excellent table discussions, including comments from those who were at the Carnegie Hall event Friday night. Check it out!
