Alas, none of those are the relevant ones I think. I'm actually rather busy visiting home, so I can only justify certain comments to myself, but I hope someone provides the links.

For what it's worth, I'm a little skeptical of lukeprog's understanding of SI --- no offense to him meant, it's just I so happen to believe he made a rather big error when interpreting the math. On the other hand, cousin_it seems to be really on the ball here. Those are just my impressions; I'm a pretend philosopher, not a compsci dude. At any rate I think it'd be just dandy for cousin_it to check Luke's posts and share his impression or critiques.
