I think the application of personas was a very interesting way to approach the issue of user representation, something that isn’t thought about very often. Being able to replicate the essential parts of human behavior has great applications not just within identifying under-representation in software U.I.s but also with any program really. I would be interested to see the various statistics and reasonings that went into calculating the five personas presented in the video, as well as limitations in how these personas can represent people.
