Google's in the news again (aren't they always) and this time they need your help. Turns out they've got to put labels on all of these images they have in their ever growing database so they got creative with a solution for it. Rather than paying people to label the images they created a game. To play just visit the Google Image Labeler page and they'll give you a random partner. You and your partner then have 90 seconds to guess names for the images. If you guess the same name you get points.
I played a few rounds and the most points I got was 600 but it was surprisingly fun. This is web 2.0, user-generated content at its best. It's also a great way to tap into people's willingness to donate a few minutes to you when you present them with a low risk opportunity...and that's sheer genius.
