Internet Retailer tells persona stories
"Persona-lizing a site" is a decent overview of the value of personas and contains some good stories about their usage and value. Unfortunately, like many articles on personas it's limited to qualitative research. The more companies I work with, the more concern I hear about making critical business decisions based solely on a few interviews or field studies. Without quantitative data to back up our personas, it's no wonder some executives are skeptical that personas can really represent all users. I love that Internet Retailer is covering personas, but I wish they had taken that coverage to the next level.
