Smart Mobs - The Next Social Revolution by Howard Rheingold: "ActiveMatch combines location information with a matchmaking database to create a new kind of service for mobile phone users. The user defines a personal profile (nickname, phone number, gender, age, hobbies etc), and includes a picture of him/herself. The user then defines a search profile (or more than one) for the person he is looking for. Finally, the user sets the 'Search distance', which is the maximum distance (in GSM cells) that the server will scan for potential matches. One cannot set it higher than 5, because searching over long distances is too processor intensive. It would also run counter to the proximity principle of the application. If set to 0, the search will occur only in the current cell."
