Idea: Insta Eat

Everybody loves to Eats and talk about Food, share the best things they eat with others and also do photography.

I am thinking to combine Instagram and Facebook to make a modern forum / social network platform but only for foodies.

SO people will capture and share food images with some reviews like
Task 10/10
Service 9/10
etc
Others will comments and give their reactions .

There are some local groups on facebook doing the same but what do you think about making a whole platform?
