While I don't really follow any food social media, I've certainly sent pictures of strange food I've bought or made to my wife or parents. Food is literally one of the most universal things on earth, so it can be interesting if I go to a country and try a dish I've never had before, and to send pictures in the process. I never really understood shitting on people posting food pics. How exactly is it hurting anyone?
