What I'd be interested to see here is whether this video posts properly from blogger

Here's the thing I notice here: look how much time is spent distracting you from actually directly interacting with him.  You might have some nice little AI tricks regarding him noticing or taking interests with things you do, but you only get real interaction after having been narratively tunnelled into a certain conversation that has certain social expectations attached to it

But I do have to say it's a neat trick.  But is it going to seem all that neat as others develop this kind of interaction more extensively?
