This is cool, though I'm partial to the idea because I like exploring methods of acquiring linguistic data. Although the data they are getting isn't entirely useful because of their methods (the answers are free form). The questions tend to not be properly answerable without some kind of context ("What will next time bring?"), but it's interesting to see a large number of answers to a specific question.
This reminds me of Open Mind Common Sense (http://openmind.media.mit.edu/) which does a much better job of capturing data that can be used as a linguistic resource.
