The future of Social Network Services (SNS) can be discovered on High School and College campuses. I believe that topic-specific “vertical” SNS’s are very important, but I also think that the model needs to be University-like – a modularized SNS. There needs to be a campus “brand” (or University) within which the topic-specific “clubs,” “houses,” “fraternities,” “dorms,” and “interest groups” can interact – somewhere where crossovers, cross-fertilization, and aggregation are encouraged – no, needs – to happen. I hate SNS sites like boompa.com – a site devoted to your favorite cars – because I am not JUST a car guy.
