Vernon Vinge's "A Deepness in the Sky". Includes very well put thoughts on the far future of software. Also his "A Fire Upon the Deep" with a fascinating take on AI, cryptography and more in a slightly alternative universe.
I haven't really found Vinge's match, although Stephenson comes close.
Most other authors in the genre are hard to read for me. They write gimmicks, or obsess over making plot devices out of memes, or never manage to make it past a collection of sketches, much less build a coherent universe.
I would love it if that series ever got finished. We're stuck on Tines world with the blight's remnant fleet approaching...
"A Fire Upon the Deep" and its differentiation are referenced in this interesting article [0].
