According to some sources it seems that Google is working on a new social network community the Tablescape were you can share photos of food. This social network is somewhat of an extension of Google+, but with more optimization for users.
In leaked screenshots of the Tablescape app there are posts from users with photos of their meals, as well as tips for taking pictures of your food. Some features of this Tablescape is the ability for users to access their “foodographs,” as well as featured posts, a dish of the day, and other opportunities to explore the social network.
At this point Tablescape seems to be something that is only being tested within Google, but probably it will be released some day.
