The layout of the VR internet-like thing in City of Golden Shadow really reminds of the whole atmosphere of Everything. That, and the fact that both the Otherland series and Everything use the term node very liberally.

The fact of people owning their own nodes, nodes with special interests, and such was all very interesting, and I almost get the same sort of feeling noding on Everything.

Just today, in fact, I finished reading Mountain of Black Glass, and while it was very entertaining to read, I was a little disappointed by the whole lack of the real cyberpunk themes and the very convincing, thought-provoking portrayal of a VR-based version of our modern day internet.

If you're interested in reading about authors' renditions of earth just a few decades into the future, I'd be inclined to recommend David Brin's Earth, which is definitely up there along with Otherland as one of my favorite books (or series of books, as it were...)
