After I read Cryptonomicon, Neal Stephenson became one of my favorite writers. Currently I am reading his Baroque Cycle that spans three volumes:
One of the cool things, besides the books themselves, is the fact that Neal debuted something called The MetaWeb, annotating the ideas and historical period explored in these books. If you haven’t yet, you should try this writer. A bunch of short stories he wrote for different publications are also available online. Check the external links on this wiki entry for these.
