Practically every facet of our society was altered by 9/11 in some way, either by the attacks themselves, or, especially, by our response to the attacks -- a response that continues to evolve. Looking back ten years later we can finally begin to get a sense of just how the country was changed, and what elements of our society we'd previously taken for granted. Starting today, with a special section titled "9/11: A Decade After", we will be examining those changes from all angles, collecting stories from across all of HuffPost, from the economy to national security, politics, education, parenting, pop culture, and the arts. The conversation starts here.
