Google Image Labeler
Newly released "game" from Google allows you to assist them in organizing their large database of images all while playing a highly addictive game. The way it works is Google partners you with someone at random and then begins displaying images. You and your partner then try to label the image and when the same word is entered it matches off and another picture is displayed. You play for 90 seconds and when time is up your score along with all of the images from the game are shown below with their links. Play as either a guest or login to your Google account to save points earned in the game. Two thumbs up if Google allows users to "cash in" these points for some sort of prize/reward (Google Checkout Credit?), as volunteers are essentially doing work on their behalf at no cost (also known as Crowdsourcing). The strategy could also benefit Google as it would entice some participants to sign up for an account and they would then be more likely to try their free services such as GMail, GTalk (which is badly trailing AIM) or the aforementioned Google Checkout. Guess we'll have to wait and see on that one...but in the meantime enjoy the game!
