Are you having trouble teaching people how keywords operate?

Here is a fun little activity using Flickr images. It’s called Fastr. The object of the game is to guess the tag that the ten images have in common. If you guess quickly you get more points than if you guess later (because more pictures are shown and the similarities are more obvious).

You’re playing online and you are playing against adults. It’s a lot of fun and ever so slightly addictive.
