Drupal Commons, Acquia’s new Social Business Software distribution of Drupal, is no doubt getting everyone excited. We’re especially seeing interest in the enterprise and public sector. The community solution is important because its an open source alternative to (social business software products like) Jive and another way to accelerate adoption of Drupal in the marketplace. Drupal Commons evolved because of countless inquiries and interest from organizations who want to use Drupal to build community sites. Not surprisingly, many other Drupal distributions evolved for the same reasons.
