Stephenson is...well, schizophrenic, as far as I'm concerned. Snow Crash feels nothing like Diamond Age, which feels nothing like Cryptonomicon, which segued into the Baroque Trilogy which I totally couldn't read, and I haven't tried Anathem yet but I suspect it's going to be striking in another direction entirely.

I loved Diamond Age, but for its own crazy, disjointed, 18,000-narrative-threads self, rather than for being anything like Snow Crash. Of course, it might help that I read Diamond Age first...
