You're absolutely right about that. If there are people who are still finding fresh ideas and are falling in love with the canon material, then this is something that will definitely be a good thing. (Also, really there is new Star Wars canon? I feel so out of the loop.) It's like they way I look at LoTR. The Hobbit is going to bring a whole new batch of canon to the screen, and I expect there will be a huge resurgence of interest there when that comes out. The cool thing about that is that there's a whole new plot and lots of new characters. If there turns out to be a whole host of new information in Pottermore, then that might pull me back and get me interested. (I'm a sucker for backstory) :-) But if it's just dribs and drabs and it's difficult to get to, while it may be the perfect kind of challenge for some, I don't know if it would be for me.

That said, I will ALWAYS adore the Potterverse. I don't care what the critical critics say, the stories are wonderfully engaging and I will always love them, even if I don't read them again. It's like the Little House books when I was a kid. I LIVED in those books for YEARS, but when the time came that I moved on, I kept them in my heart even though I never read them again.
