We've had a number of clients ask us this question recently. Different people will tell you different things about what Drupal is and why they use it. For Pushing7, it's all about knowing that we're building sites on a flexible platform that can evolve in virtually any direction. What this means for our clients is is that when we're presented with questions about whether we can add a feature or display content in a specific way, we can answer the question with a resounding "yes!"
