For people who have a camera in their hand all the time dont miss an opportunity to take pictures of things which are rarely noticed or are of something which does not interests people but does interests you. Noticings is an online utility which has taken this idea to next level.
It’s like a game, You find something noticable or whatever you think is worth and tag it with noticings and geotag with location where you took while uploading to Flickr. Every day this service finds photos and then gives a point. The more you make points the more you are noticed ;). Find more about Noticings.
