I find this website about Airline meals strangely compelling. My initial reactions were "what the fuh?" and astonishment at the scope of it. 10,000+ reader submitted images and reviews covering over 400 airlines.
It turns out to be one of those wonderful success stories that crop up on the net occasionally, someone starts a niche interest website that strikes a cord with people and it takes off (sorry about the pun). Read the 'about AirlineMeals.net' for the interesting history of how the site came to be. Some airlines are now actively using the customer reviews to monitor the customer reactions to their meals and the reviewer photos to monitor quality control and to ensure the cabin crews are presenting everything properly. The Dutch graphic artist who started and runs the site has now added other airline related ephemera such as vintage meal pics and advertising, and related airline food topics such as lounge food and behind-the-scenes of catering facilities.
As I said, strangely compelling.
Updated: I just noticed that the Aussie paper the Sun Herald recently did an article on AirlineMeals.net which makes for interesting reading
