Don't know about how much it has helped my hunting, but it certainly helps my day go by faster at work.

All kidding aside, I've learned quite a bit in the area of management, equipment, etc., but the most interesting thing is how others view hunting in their own little world. (i.e. "What's a trophy?", "What is ethical?", "Who makes the best bow, broadhead, arrow, release, sight, rest, etc., etc.?")
