So, first of all, let's all discuss and freak out over the regeneration news, shall we? Since everyone's going to do fantasy casting, let's go ahead and do the requisite open thread in which we all speculate over who they'll cast. But why make this blog like every other speculation thread? So let's put up a constraint: no white male choices. Women and minorities only.
Second, because everyone is going to ask, yes, this does change the plan for the blog's endgame. There's no point in getting four entries into the Twelfth Doctor before ending the blog - it's just a rubbish endpoint. So instead, barring major plot twists, Matt Smith's regeneration story will be the final post of TARDIS Eruditorum. Obviously there's a high chance of me going back and doing the Twelfth Doctor at some point, but equally obvious, I'm not going to make any firm plans on that right now.
