Resumen
This article is a research into the social dilemma issues underlying cooperation and has identified the importance of persistent identity and repeated social interaction in promoting participation and cooperation and in reducing selfish behaviors. It also focuses on how to blend digital and physical spaces for ubiquitous community participation. Traces of a person's activities and behaviors (such as interests culled from what they read), as well as other people's interests in an individual's contributions, are important to maintaining a persistent and up-to-date identity for that person. Several social browsing tools enabled people to become acquainted with and then be held accountable for their behaviors on the site. The Plasma Place display was popular among conference attendees who noticed, touched and talked about the Plasma Place screens elsewhere throughout the conferences. The display was also an effective advertisement for the online community spaces. Not only did attendees contribute content related to the conferences themselves, some joined as members of the online spaces. The sharing of digital media artifacts is common and involves people with a high level of curiosity about experimental technology intervention.
