I registered simply because, as a retired airline pilot with an FAA ATP License, the FAA has a ton of info on me already. A little extra won't hurt. If you don't think that the 800,000 or so drones purchased over the Christmas season doesn't have an impact on aviation as a whole, consider this: A friend of mine is a helicopter pilot for Life Flight Air Ambulance. That company, in the last week, has prohibited their pilots from flying below 1000 feet MSL. What does that mean? It means they need a weather ceiling of at least 1500' to fly as opposed to less than a 1000' ceiling. This means that they may not be able to fly a potentially life-saving mission due to a restriction imposed because of the possibility of a collision with a drone in adverse weather. And that's only in consideration of the operators who are complying with the 400' mandate. I agree with the concept that you are, indeed, operating an aircraft and therefore need to exercise safety and good judgement.
