Copenhagen.
We're now starting the second keynote here at the AoIR 2008 conference in Copenhagen, by Rich Ling. He begins by asking how technology has become part of the 'social woodwork', how it is being domesticated. The Internet, he suggests, is actually a quasi-broadcast medium, in spite of rhetoric to the contrary - a one-to-many metaphor holds sway for many of its services (excepting email, of course, but certainly this applies for many Websites).
Mobiles, by contrast, are a point-to-point form of communication - SMS and mobile voice communications account for the vast majority of usage, and the mobile telephone enables individual (rather than geographically fixed) addressability. Mobile phone communication is also a relatively intimate form of communication - and while new phones and new services may change this, most people use relatively old and limited phones which do not cope with such services particularly well (the most popular phone in Norway, for example, belongs to a now discontinued and comparatively ancient line of phones).
