Stephen Kaufman of The Linguist Method details what he sees as some of the primary benefits and advantages that the internet has to offer language learners. You can read or listen to his helpful article here. In the article he discusses a number of different things, but what I found most valuable are his thoughts on the primacy of input and the idea of the importance of learning new vocabulary. It is an interesting article and useful in thinking about how we go about learning languages. As a note, Kaufman's free language learning program is called Lingq. It is a great program with something like 12 available languages to learn. Unfortunately, Turkish is not yet one of them.
