With the advancement in technologies to locate individuals, there has been an emergence of information systems that link People-to-People-to-Geographical- Places, labeled P3- Systems. While various P3-System services have been proposed and deployed, there is limited knowledge on people's desires and attitudes towards such services. We used the P3-Systems framework to guide a survey study of the impact of 'place' on people's social information needs and willingness to share personal location data. At fourteen different place types (Restaurant, Post Office, Etc.) in Manhattan, New York, we surveyed 509 individuals over 3 weeks. The vast majority of respondents expressed a desire for and willing to share their personal location data. E.g., 77% of respondents were willing to reveal their current location to others (17% with complete strangers).
