“This is by far the nerdiest episode we ever did, so fasten your seat belts. In his session at UXcamp, Tom said: “Personas – love ’em or hate ’em – you can’t not use ’em. Either you have zombies, or you have living ones.” In this recording of his session he talks about different kinds of zombies like Mirror Personas, Undead Personas, Unicorn Personas or Stupid User Personas. He gives advice on how to avoid these fellas and how to make good use of living personas during a project. As a bonus, Tom explains why 37signals doesn’t need personas at all.” (UX Café)
