Or, since less than 3 percent (+/-0.2 percent, last I checked) of
Flickr photos are under any sort of public license, and the quality of
labeling leads to remarkably frustrating search attempts, why don't we
add a way to user-source the photos ? The mobile web UI or mobile app
could have a "hey, we notice you are at a location that needs a photo,
would you mind terribly?" tool for sites that hadn't been tagged yet.
