i'm a couple of hundred pages into this now. as i expected, it's not so much about the plot (which hasn't really happened yet -- it's still mostly unspooling backstory), but more a chance to wallow in details and trivia.
it's being a fun read, albiet a bit overblown in parts. only two geneological diagrams so far. no graphs of sexual desire vs phase of the moon or whatever "cryptonomicon" had.
