It's becoming less socially acceptable to be bad at a hobby. I kind of like football but wouldn't dream of calling myself a football fan in more knowledgable company.
I suppose we run in different social circles. I’m not sure what “bad at a hobby” means as the reason I hobbies is because they are fun to me.
I list kayaking as a hobby not because I’m competitive and awesome but because I think it’s fun to float down a river. I suppose if a company expected me to be good at my hobby and judged me because of it, I wouldn’t want to work with them because their culture probably has other stupid parts to it too.
