Commercial Drupal

I've looked at Drupal from afar and noticed that there is an appreciable
support community around it as well as impressive endorsements. However, it
seems to me like their primary focus is to build communities. I'm receptive
to the notion of nurturing loyal customers through a sense of belonging.
However, what has been your experience with deploying Drupal in a commercial
environment? Is there a certain level of undoing required to roll out a
Drupal site with an emphasis on information for the purpose of commerce vs.
community?
