It seems that most of the users fail to tag their photos to a place. Even professional travel agents upload 100s of photos of a place in a folder called for example "Agios Nikolaos" or whatever but the photos are not tagged. Perhaps an option to do batch tagging could reduce this problem. For example when you make a folder (other than the Неразобранное "unsorted") you could have a clear option to automatically tag all the photos you upload in that particular folder to a particular place.
