Duolingo launched exactly one year ago today. 1 year, 2 mobile apps, 3 new languages, 4 million people learning a language for free — and we're just getting started :)

Happy birthday Duo! And on June 20 is my own Duo anniversary :-) Exactly a year ago I found a link to Duolingo and decided to try it just for fun. Today I'm finishing my second Duo tree! Thanks for all this new experience and special thanks to designers for the awesome interface that attracts you once and forever!

In my country, we don't say "happy birthday", we say: "many more years". So following that tradition:

Duolingo, I wish you many more years!!! Live long and prosper ;-)

Congratulations. My wife showed me this site a few weeks ago and I've been slowly hacking away at the German material ever since. As Paulenrique mentioned, this site does seem to have addictive qualities...

Happy Birthday and Congratulations!! The whole DuoLingo Team should be very proud. Opening up the world of languages and learning to millions of people around the world is is a great and noble gift. Plus the very innovative nature of DuoLingo makes it a true hallmark on the modern internet along with learning sites like Khan Academy. Here's a toast for many more successful years of bringing languages to peoples around the planet!!

Happy Birthday Duo! Thanks so much for all your hard work putting this stuff together - it's helping me learn French so much faster! I'm looking forward to getting to the end of the tree and starting another language after this one! You guys rock and I hope you get to eat lots of cake. x

Well done guys on your first anniversary! I joined a couple weeks back and I've found DuoLingo to be terrific. I look forward to your growth into non-European languages soon! Perhaps Arabic, Japanese, Korean, and Russian? All the best in your second year!

Happy Birthday! I am so grateful for this service. After years away from speaking French I am relearning it and learning how to write it better than I ever did. I'm two years away from a PhD and regaining my bilingualism is going to be a huge asset when I am finally looking for my dream job in public policy (in Canada). Thank you so much!
