I'll admit that I was sort of underwhelmed by the YouTube announcement, (though the visual effects were rather cool) just because the rather vague detail didn't sound all that unique - it's what, an online read-along thing? With a shop to buy audiobooks and ebooks.
But then I went and checked out The details from the UK press conference and now I am much more interested.
An interactive site with character backstories, exclusive information about the writing process, cut scenes and other stuff?
Plus, it's apparently like an official sorting community thing.
So there's that. While there are things I might have liked more, the combination of encyclopaedia-ish stuff and social thing sounds like fun.
Though I sure hope all their servers are up for the demand.
