> There's small payoff for an American to study a 2nd language.

If you are only looking at economic payoff.

I've been to countries/cultures (Latin America) where I feel that if you don't have a grasp of the language - you can only be a tourist. Reusing cliches but not being able to speak a language - you lack the passport to truly immerse yourself - you'll only be a tourist if you can't speak (to a point) the language.

I'm really looking for an app that will find Spanish texts for me to read that have words that I don't already know (e.g. smart enough to learn what your working vocabulary set is). Since I'm starting out - almost every text will have words I don't know. Anyone know of an app geared towards reading and vocabulary building (and possibly reading material discovery)? Or do we have to build one (it will be a little harder because of the conjugations, m/f variants of words)
