I don't have much respect for anyone who labels themselves a foodie. Unless volfanjo does. About 75 percent of his posts are about food and I like that guy.
Hipster. Foodies enjoy trying new cuisine. Hipsters enjoy trying new clothes, caramel lattes and crappy music.
Foodies are annoying because I'm not sure they actually like food. They like the status that comes with talking about food, taking pictures of it, and being generally annoying about the "best pho they've ever had". That said, I basically plan every trip and orient my entire day around food, so I don't have much room to talk.
Also as someone who does enjoy food I am greatly anticipating the slow death of the organic, free range, farm to table movement. It isn't that I'm against the notion, I just hate people (foodies!) breathlessly talking about it so much.
Kale and Brussel sprouts are the two veggies I cannot make myself like. I've taught myself broccoli with feta cheese isn't half bad.
You should try selling to some of those people. I do agree with the principles of eating local and getting away from centralized monoculture ag, however there is an elitist element and over the top environmentalism element mixed in.
