Snow Crash came out about 8 years after Neuromancer and 17 years after Shockwave Rider so I don't think it was groundbreaking. Having said that, I did enjoy it and I do see modern weak knock-offs of Snow Crash that have gotten praise from the pundits in the last couple of years.

Cryptonomicon was awesome but too long. I wish it was cut down.

I loved Diamond Age. I still think about it.
