Let me say first that I am really enjoying this book thus far. It is much more coherent than some of the other books we've read, flows better in my opinion, and gut wrecnchingly funny (ok so maybe I'm exagerrating a bit here but let's just say it's a plus when you have vocal representations of your amusement).
There are two things that I found really interesting. The first was all the technical jargon about symbol logic. I can see how alot of people would not like it but I for one enjoyed it alot. The way it was presented made it really readable. There was a speed an excitment to their discussions which just rubbed off onto the reader. Not to mention Randy's accent was pretty funny, although at certain points it seems like his accent has disappeared totally.
The second thing which I found really interesting was the interactions with Goto Dengo. I know it starts out pre-WW2 but the fact that they interact at all is really something. To the point I've read, I can't tell if we'll see Goto again or if (assuming Crytonomicon has as huge a character list as Infinite Jest) he's just one in a multitude. I hope he isn't just the token Asian guy to temper zealous Asians from claiming Crytonomicon is racist or something like that.
