Youth and Politics of Place

 Spatially co-present
 Public Transportation and Street
 Freedom of motion
 Prohibition against voice calls on public transport and
many restaurants
Messaging and
Mobile Email
 Used in particular places for particular
kinds of communication
 For lightweight contact
 When unsure if recipient is available for
communication (eg. Late night)
 When there are limits to voice calls
 Classroom, public transportation, restaurants

intimate friends
 Couples, in particular, maintain ongoing
exchanges when apart
 Expectation that these friends/partners are
always available

continuous connectivity and background

“Are you up?”
“I’m walking up the hill now”
“Good night”
“The TV show was awful wasn’t it”
“I was out drinking until 2 and just woke
up”
Enhancing Co-presence
 Augmented co-presence



“This lesson is a pain”
“Where are you standing?”
“Try asking so and so”
“Check what time the train leaves”
 Extensions of co-presence
 “Thanks for the lift”
 “I forgot to give you back the CD”
I am constantly checking my mail with the
hopeful expectation that somebody has sent me
a message. I always reply right away. With short
text messages I reply quickly so that the
conversation doesn’t stall.
