I was just going through some work I did a few months back and found some personas I wrote based off of some interviews with (mostly) Drupal developers.

Kent Bye of Lullabot interviewed me (and other team members, as well as a whole lot of other Drupal community members) at Drupalcon.

One little practical issue I found myself thinking about during the Drupal study was accommodating different styles of working while evaluating a web app.
