The iPod as a social networking tool: "Well, their iPods have allowed them to create personal playlists that they carry along as a soundtrack to their lives. When they publish their playlists to Rendezvous networks in their dorms, other students surf those playlists to get an idea what people are like."
Another part of this article really reminded me of LifeBlog: "Using the touch wheel, they scroll through the whole collection in a couple minutes, presenting a kind of time-lapse view of their lives. It lets them share in a few minutes a lifetime of experience and discover things in common."
I find it weird that, despite the increasing availability of bandwidth, having your stuff with you physically is compelling. I suspect a generation that grows up with 3G may feel differently.
