The beginning is actually really tough going as a completely new reader today. It's just so ridiculous. I can see where he was coming from, as I grew up in that era, but it's actually pretty bizarre now given the reality is nation states, religion and banks turned out to be so much more powerful than corporations.
Which is one of the perils of predictions in ageing sci-fi.
I've been on a sci-fi kick recently of all the classics I never read (William Gibson, Ender's Game, The Mars Trilogy, Forever War, Starship Troopers, A Canticle For Leibowitz, Philip K. Dick, Hyperion Cantos, Ringworld) and re-reading some I've not read for a long time (Foundation Series).
I personally found that Snow Crash is by far the most dated book. Even Ringworld and the foundation series were better.
Some of the space opera, on the other hand, was so earnest and certain that we'd be flying around at light-speed by now you feel almost disappointed for the authors.
All cyberpunk is like that, for reasons that are pretty obvious.
> Even Ringworld and the foundation series were better.
Of course. Physical reality changes much more slowly.
And when I refer to Foundation & Ringworld I meant that they are from the 60s and so have some weird cultural ideals as well as some (unintentional) misogyny & racism in the foundation series.
I've a major in Physics and it took me a couple readings to figure out all (well, most of) the connections therein. My favorite game to play while reading Anathem was figuring out where are the borders between historical fact (translated into the fictional world of Arbre, of course), current hypotheses within present-day science, and just downright fiction. Quick quiz: is "geometrodynamics" Stephenson's invention, or a term used in the real world? You get puzzles like that at every step, some easier, some harder.
A few examples that stand out:
Actual history of science - well, Thelenes, Adrakhones, Saunt Tredegarh, Saunt Muncoster, etc. (again, real people disguised under the mask of Arbran characters)
Current hypotheses - the whole Multiverse thing, the Fraa Paphlagon / Hugh Everett parallel.
Out-and-out fiction - eh... this is harder. The Wick, maybe?
And then there's Fraa Jad, all alone in a category of his own. :) I daresay one of the most striking, memorable characters in all sci-fi - if you get the point of the whole book.

The Baroque Cycle is a massive piece of work spanning 3 volumes, comprised of 8 nominally independent books. If it seems intimidating, just try the first one and see if you're not hooked. I'd love it if there was twice as much material.
Anathem is by far my favorite. Its hooks take longer to set, but for me they set much deeper. There is a lot going on in this book, and it will truly blow your mind if you let it.
