CalorieCount.com, which launched in 2004 and was bought by the New York Times Company/About.com in 2006, has always been free to users. But like many ad-supported sites, CalorieCount is looking for another way. Last week the company introduced a new freemium feature: a social network based on your food logs. Post your dietary activity, and the community leaves supportive comments. CalorieCount is hoping that once users get a taste of what it’s like to get caloric feedback, they’ll start craving the premium product: feedback from a professional nutritionist. CalorieCount is offering different options for users who want to talk to a nutritionist, via daily feedback in the comments, in a weekly consultation or by phone, in a service called Calorie Camp.
