Reading & thinking about the debate about content vs. connections, I was reminded of Trepia's proximity-based instant messaging application, where the "buddy list" is really more of a "neighbor list" representing other Trepia users who are logged in nearby. My initial impression of the tool was that proximity is based on a common wireless access point (or network of APs), but I believe that the notion of proximity was expanded at some point to include larger geographical areas and may even have allowed users to specify a location they want to be associated with (regardless of whether they are in that location). The Trepia client includes a user profile, enabling users to provide some content, besides location, that might help to provide the catalyst for a chat. I can't find many people talking about using it (outside of the period last spring/summer when they received a great deal of press attention). Some commentators have complained that they never saw anyone on the buddy list, and others complained that the geographic expansion was far too broad, showing too many people from too far away. In any case, I tried to visit the site today, and now see "Red Hat Enterprise Linux Test Page". If anyone knows the whereabouts / status of Trepia, or has any recent experiences with the tool, please post a comment. Thanks.
