So, JKR said Dumbledore is gay.
And yes, I agree that it's not a surprise.
What surprises me most about some of the discussions I've read concerning JKR's comments is the insistence that an author cannot comment on or add to her own story. That the story is locked, sealed, and unalterable once it is in book form.
Me? I'm fascinated by idea that the story exists independent of the form used to tell it, whether that form is book, song, video, movie, TV series, interview. The form picked influences how the story can and cannot be told. And now, the Internet adds to the way that the story can be shared. I actually find it rather exciting, and full of possibilities.
Edited to add: Wizards Wireless is compiling a list of all posts on this most recent JKR interview. Go to W2 & let her know you've posted to be included in the round up.
