There’s a very interesting piece on how people use different channels for different types of communication. This is a perfect example of how ethnographic techniques can really add to our understanding of use. I also think it’s interesting how many design/tech folks I talk with are convinced that technologies like SMS are drastically increasing the network of people we communicate with. I think this is primarily based on watching teens (primarily Asian) and tech enthusiasts use the technology. Based on this study, normal folks only SMS with 4 or 5 people. It’s an intimate network.
