Stephenson's novels in general are like this, although Cryptonomicon for one certainly has better character development than Snow Crash: they're a disorderly jumble of whatever ideas Stephenson thought were interesting at the time, wrapped in a skin of plot, and enfleshed in the characters that surround, encounter, and explore them. Stephenson sometimes jumps the rails entirely, writing long monologues, dialogues, and digressions that barely refer to the characters or plot at all, just because he thought the ideas were neat (most of Randy and Pontifex's discussions in prison, The mathematics of Alan's bicycle chain, a good stretch of Hiro's discussions with the Librarian (although nowhere near all of them), and Hiro's adventures in Flatland on the raft (you can just feel the seeds of In The Beginning Was The Command Line, struggling to get out)), or for reasons known only to him (probably because he thought it was funny) (the TP memo, the stockings/Van Eck... thing). To some people this may be seen as a disjointed, overhyped, overcomplicated mess, but to the right sort of mind, it's an almost magical experience.
Curiously, these sorts of people tend to be heavily into computing, which is why Stephenson pervades that culture.
Or that's wrong, and I'm just completely mad. That's also a possibility.
