Socialstream research, user studies, and design

I just blogged about a capstone MA project at Carnegie-Mellon called Socialstream, which seems to be a prototype of the Universal Activity Streams concept that Google will launch next year. The Socialstream team has done a good job of high-level documentation on its research process, including user profiles, contextual inquiry, and iterative design. It tends to overdetermine user types, based on a quick reading, but still it's a nice example of an interface design process.
