The Acquia podcast has released a special episode today spotlighting a video interview with Voices of the ElePHPant host Cal Evans and Jeffrey (jam) McGuire of the Drupal community. They decided to do a joint podcast, combining the Acquia and Voices of the ElePHPant podcast, giving you a look behind the scenes at Cal himself.
They talk about how Cal became involved in open source, how he discovered Drupal specifically, his involvement in the PHP community as a whole and where he works/what he currently does. They also talk about why Cal thinks PHP is such a success and his own "virtual user group" project, NomadPHP.
You can catch the interview either through the in-page video player or directly on YouTube.
