This month at the Toronto user's group meeting, Bob Fabian presented a talk on CIPS's (Canadian Information Processing Society) decision to convert their main site as well as 35+ regional sites to Drupal.
Neither Bob nor CIPS is a client of Be Circle, but the reason they choose Drupal was somewhat surprising. Upon reflection I think it is something I intuitively knew and couldn't help but write about it here.
So what lead to the decision? Why did CIPS choose Drupal? (I'll give you a clue: Its Drupal's greatest asset).
