After the first keynote at AoIR 2009, I'm now in a panel on last.fm that begins with Nancy Baym. She asks what the term 'friend' means in a social networking site; this both in an interpersonal context and in the context of society as a whole, where some suggest that the term 'friend' is losing its meaning through its use on social networking sites. Last.fm was founded in London in 2005, and now has more than 35 million users; it is highly international, and based in the first place on the use of audio scrobbling application which share what its users are listening to.
