Anyway, since we are talking about characters, Pottermore is filled with them. JK Rowling is breaking ground in the area of ebooks and ecommerce so I'll be watching closely not just for the literary aspects, but for the marketing ones as well. For those interested, Nathan Bransford wrote a recent post on the topic, Why the Harry Potter E-books Are and Aren't a Really Big Deal. With so much going on with publishing, you'd be crazy not to at least be curious, right?
Have you unlocked the magic or signed up yet? Are you planning on it? I'm taking my son with me on this journey so I'm sure we'll have loads of fun.
