Bay Area–based food-plus-social-networking site Foodily, which indexes millions of recipes from across the web, launched in beta today and is apparently generating some buzz, as they say. It’s a recipe-sharing site with the added functionality of knowing what your friends like (assuming your friends are on there), and knowing what your dietary needs and dislikes are (assuming you tell it those things). It was started by two former Yahoo execs, one of whom, Andrea Cutright, tells USA Today, “One of the most social things you do is eat. People love to plan meals, share recipes and go out to eat.” So, she figures, the food world needs its own Facebook. It’s ambitious and could end up being a lot handier than those fork ratings on Epicurious. But don’t they need to wait for critical mass to join up — sort of like Facebook did — before the whole social part of this really functions? Anyway, see the explanation for yourself via a cartoon, straight ahead.
