How can you learn foreign languages online? Last week, The New York Times outlined a good number of options for its readers. And, for days, the article remained one of the most widely read pieces on the NYT site. Today, the paper issued a followup post, highlighting yet more ways to learn languages digitally. And happily our collection, Learn Languages for Free: Spanish, English, Chinese & 37 Other Languages, got a small mention there. When taken together, these two pieces spell out the different educational opportunities fairly well. Some of the sites mentioned include LiveMocha.com, BBC languages, and Mango Languages.
