Snow Crash is great. I actually just finished Zodiac yesterday and only realized after the fact that it's 30 years old. I'm starting Seveneves now, and it's already blowing my mind.
I've been meaning to read a number of different things, many from friends I've convinced to jot down in my reading suggestions spreadsheet.
It took a new local library opening up, and a holiday, for me to finally get to Snow Crash. I suspect I might be reading a few more of his works very soon.
I don't think I've read any of the others, though I may have started Seveneves at some point, but I did read "The rise and fall of D.O.D.O." (just before Snow Crash in fact!) which I highly highly recommend as well.
It's really good; as I was reading it I would stop and check the date it was authored. It holds up very well.
