Memrise

Memrise is officially my new favorite website!  Spearheaded by one of the world memory champs, it builds on the idea of having an image or phrase to remind you of a specific thing to aid in remembering, rather than cramming.  The website offers lists in languages, history, geography, and such things as Pokemon (yes, really).  Apparently the Chinese lessons are especially cool as the characters animate into their descriptions, which is awesome!

For example, to remember the word for where in French, oú, there's a picture of Scooby Doo, which helps you with both the where part (Scooby Dooby Doo, Where Are You?) but also with with pronunciation (oo as in rhymes with doo and you).

Each session lasts about five minutes by design; the idea being that you can only absorb a certain amount at a time, and coming back to material frequently is how you learn it.  Quizzes vary in the number of choices you have, whether you're going from French to English, or from English to written French, it's wonderful.  And, there's an added points system to keep you going - but honestly, I find it pretty addictive regardless of the points.
