Holy crap, what a weird story. A far far far far future universe where godlike posthumans do stuff that I didn't even understand in the name of terraforming and running the universe for the common folk. There is a
wikipedia entry for this novel, which is made up of 5 previously published short stories. A bit too weird for my liking, although I did finish it and the general story made sense. I dunno if I can really take the idea of "Dark Matter Talents" too seriously though.
