I read it last month and really enjoyed it. I didn't have much trouble keeping track of names and places*, and I liked the epic scale. The depictions of superintelligences were better than a lot of others I've seen, and the aliens were, if humanlike in their behavior, interesting in their physiology. The "tantalizing me with incomplete world-building details" was a plus for me, but if it's not to your taste that's understandable.

*There is one thing I never understood though: ubj Gjveyvc bs gur Zvfgf' pbzzragf nobhg urkncbqvn jrer eryrinag. V tbg gung rl jnf evtug nobhg gur mbar fgbezf orvat eryngrq gb gur oyvtug, naq gigebcrf fnlf Gjveyvc jnf evtug nobhg rirelguvat, ohg V qba'g frr jurer urkncbqvn pbzrf va. Could someone explain that?
