In our culture, we’re suspicious of strangers. They’re a threat. They lurk in shadows. On the Web, however, strangers are the source of everything worthwhile. Strangers and their utterances are the stuff of the Web. They are what give the Web its matter, its shape, its value. Rather than hiding in our tents and declaring our world to exist of the other tents near us — preferably with a nice tall wall around us — the Web explicitly is a world only because of the presence of so many strangers.
