Steve Irwin will definitely be missed in terms of his entertainment, and his educational value regarding behaviors of wild creatures. Certainly, his cause of death was a rarity. I hope people will learn a healthy respect for nature from his work as well as his demise. I just think as photographers, it gives us a little pause to think about what is reasonably safe and what is flat out stupid when we're trying to get that great shark shot, or shooting a Humpback up close and personal, etc. Know thy subject, and keep your distance.
