I'm putting together an app where users can upload photos of dishes from the restaurants they visit. Right now I'm debating on whether or not to include the ability to comment. What I'm trying to determine is if this feature is introduced would it add to the value of the photo itself and/or the overall user-experience.
Often times for photo-centric sites such as Instagram, Facebook, and Flickr I've observed that comments left by friends and strangers most notably come in the form of identical compliments (Awesome photo!, Nice, etc.) or questions that receive little to no replies from their uploader.
One of the main goals of the app is to help users find top rated dishes. Images that represent these dishes take this one step further. Would implementing a comment feature help aid these users that much more or only add redundancy?
