For some reason it took me quite a while to finish this book while I devoured Accelerando. I've read a few of Stross' books and generally like his style. This time however his use of jargon put me off. I can pin it to a single word: "wave". When the book was written Google Wave was "the next thing" except half a year later it wasn't. This made the whole book feel dated to me. The final twist with the identity of ... somehow didn't get me, and I believe there is a previous book with the several of the same characters that I haven't read. All these factors made me enjoy the book a little less.

Despite these personal issues I think this is a good and fun read of a future where reality has become augmented and spam turns smarter every day. It's not too far into the future and I can easily imagine many of his visions coming to pass. I like the setting in Edinburgh as well. The 2nd person perspective is something you get used to after a couple of pages.

It's neither a quick nor an easy read with dense writing, a slow-starting, complicated plot with many twists, turns, and viewpoints. This book suffered from my not having enough time/concentration. This is more of a vacation read.

PS: as the title suggests: you better be an internet nerd, or you won't get half the jargon anyway. In that respect it seems even worse/better (depends on your pov) than Accelerando.
