Ask HN: Review My App - Popling.net, Learning without studying

It's a website + AIR app for people who want to learn, but lack motivation. I built it because I wanted to learn Spanish but I'm too lazy to study.

The desktop app shows you a flash card every few minutes (you decide how often) through an unobtrusive Growl-like notification window. If you aren't busy, click the notification to answer the question on the flash card. If you are busy, ignore it and it goes away. It works especially well for getting started with a new language.

Help me make this thing better!
