I'm assuming this whole conversation is about non-relativistic quantum mechanics.
But obviously reality is not about non-relativistic quantum mechanics. So whenever a discussion about interpretations is brought up, I think it is dishonest to argue FOR a partial version of it that really has nothing to do with reality

Eliezer's gung-ho attitude about the realism of the Many Worlds Interpretation always rubbed me the wrong way, especially in the podcast between both him and Scott (around 8:43 in http://bloggingheads.tv/videos/2220). I've seen a similar sentiment expressed before about the MWI sequences. And I say that still believing it to be the most seemingly correct of the available interpretations.
I feel Scott's post does an excellent job grounding it as a possibly correct, and in-principle falsifiable interpretation.
