I completely disagree with your post on this topic. However; I can understand your personal frustration in cherishing solitude in a sport you love.
We have to remember that the world is for everyone and that sharing is one of the greatest gifts anyone can give. Isolationism in a sport is cancerous and will lead to its demise. Positive stewards and excellent ambassadors are what we need to grow the sport and protect its natural resources.
I think it is great when others share their photos and reports. It helps me learn and share in their joy! It grows my interest and support. Sure it can increase boat traffic of others who share similar interests. It will also support and protect the sport by having passionate and caring people involved such as yourself!
