I read the article in Wired and was intrigued. Having briefly played with the program it seems to me it could be infinitely more useful if the "questions" could be images. Memorizing the constellations for example would be considerably more useful if you could look up at the sky and actually point them out.

Does anybody know if this kind of functionality exists in another program (or if I'm just missing something?).

Two Airlines, two totally different experiences:

1.
I showed up late for a Westjet flight a few years ago. The plane was gone and I hadn't even checked-in. It was totally my fault but I needed to get to Winnipeg that evening. Westjet took pity on me and refunded my money on the spot so I could book a flight with another carrier! I have loved WJ ever since and always fly domestically with them (even if AC or another carrier is offering a lower fair).

2.
I booked a flight with Air Canada to the UK (again it was a couple of years back) but then had to cancel. AC wouldn't refund my money (1200 bucks) but instead gave me the ticket value (minus penalties) for use on a future flight with them. Fair enough I thought, until I actually went to use the credit for another flight. That's when I was told that my initial ticket purchase had been for a discount fair but that my credit was only good for a full fair price. Total scam. Price from Calgary to St. Johns at full fair price? $4000. To Vancouver? 2500. To Edmonton? 1500. I gave up. The only way I could use my credit was to give them more of my money.

Viva la WestJet and death to AC!
