Went to Germany in October for the first time for a large-number birthday. Did Duolingo for about six weeks prior: It gave me no ability to speak actual German -- aside from "Danke" and "Schuss," but it did enable me to recognize enough words help me with directions, navigate via public transportation and pick out different varieties of beer and sausages on a menu. Thankfully, with the impact English has had on the world through rock and roll and movies, pretty much everybody I encountered in Berlin spoke or at least recognized English. This was less true in Vienna.
