This is bloody brilliant... attach an image, video, comment to any product that has a bar code on it for others to see and add to.

Now, the activist in me thinks that this would be a great way of bombing unethical products, alerting potential customers to the origins and production cycle of environmentally damaging items.

Or alternatively, the socialist in me would say that this would be a great way for the government to attach health ratings to food items for example.

Or even, the advertiser in me would attach freebies, branded content, details of provenance, etc to the product. Anything that would enhance a products appeal beyond what it's specific benefit/purpose is.
