Excellent, thank you! We will be adding many features in the next few months, but my favorite is individualized but automatically generated language courses. We will use the technology you see on the site's front page to present users with sentences on an individualized basis depending on what words they already know. If a user knows the 500 most common Spanish words, for example, we will show them an authentic sentence that uses one or more of those 500 words plus the 501st most common word. As the user demonstrates knowledge of more words, the set of possible sentences for that user will gradually increase. This will reinforce existing vocabulary while building new vocabulary as efficiently as possible.
