Happy New Year from the Duolingo Team! Thank you all so much for your support. Our resolution is to make Duolingo even better in 2013.
Is there a possibility of more grammar being incorporated into the training drills in later updates to the site? I also think it would be nice to have a more in depth explanation of certain grammatical differences between English and the languages you offer tutorials for. This site is an excellent starting point to learn the languages you guys offer; the drills that are presented are very interactive and comprehensive. Is there any chance that more languages will added in the future, and if so, would a database or index of vocabulary be expanded upon for each (as well as the grammatical details)?
