This chapter looks back on and reflects over the mobile use of an online community for Swedish teenagers, an early social media, and discusses its relationship to current social media. Analysis of two months of log data and 100 surveys on teenagers’ phone use showed that the phone use mostly took place during times of the day when teenagers had social time and was not influenced by the availability of a computer. The phone made the community access more private compared to the computer, but teens did share the use when they wanted to. The cell phone bridged the online and offline social communities and allowed teens to participate in both at the same time. The online community was not only a place for social activity online, it was also a social activity offline that was carried out face-to-face with friends.
