little brother caller ID

chapter 2 notes that it’s really easy to fake the return number on a caller ID? Doctorow even suggests the reader “google ‘spoof caller id.’” Well ... did you google it? Why would Doctorow suggest we do this? How does his call to action pull the reader into the novel? Connect Doctorow’s suggestion to what we know of him as a writer and an Internet activist – see, this is why knowing some background about him is VITAL.
Since the novel is set in near-future San Francisco, it would benefit you to actually know WHERE it is located in the USA and some of the basic information about the city – GO FORTH AND RESEARCH, and write some notes.
