I regularly visit Chowhound, Facebook and Instagram and at all 3 sites I engage in a lot of food discussions, post food pics and make and receive recipe and restaurant food recommendations. I get all jazzed up when April Bloomfield o Marcus Samuelsson or some other chef I admire comments on something I posted. I follow many chefs on FB and Instagram... Jamie Oliver posts great photos on Instagram, by the way.
How about you? How do you use social networking to discuss, learn about, and enjoy food?
