What’s LBSN
The LBSN workshop’s Web site defines LBSN
as social network services where people cantrack and share location-related information
with each other, via either mobile or desktop
computers. As location is one of the mostimportant aspects for people’s everyday lives, a
lot of novel application scenarios can be
supported by LBSN

Generate $3.3 Billion by 2013?

Brightkite, GyPSii, Pelago and Looptcould reach revenues as high as $3.3

• Current LBSN application don't have manyusers and that the chances of finding any of your friends on them are relatively low fornow
