Am I missing something? Isn't Mechanical Turk the community of real people? Or do you think "we'll also use..." means that they're using something else? I didn't get that gist from the full quote:

"After you send us a photo, we'll store it on your Amazon Remembers list (similar to your Wish List) in the app and in your Lists at Amazon.com. For fun, we'll also use a community of real people to find product matches on Amazon.com."
