Duolingo just crashed for me. Does anyone know why?
I had it happen as well. Pressing the final continue after testing out a lesson led me to Error 500 page (instead of the congratulatory screen, the mean owl!), and couldn't access anything on the site for a couple of minutes. This site http://www.isitdownrightnow.com/duolingo.com.html said it was up and reachable at the same time I was seeing the error, thought it was a problem on my side.
