Italki

Italki is a community website for learning foreign languages. The key word here is 'community', italki doesn't provide language lessons of its own. Instead, the member of the community is the one giving language lessons to other member. Member can apply to become a language teacher, whether professional of informal. Professional is meant for experienced teachers who can make proper instruction in the languages they teach. They also expected to have a curriculum for their lessons. Informal teachers are usually native speakers who willing to teach other their mother tongue. These lessons are not free though, the currency in italki is italki credit with rate 10 italki credit = 1 dollar.

Fortunately, for people who don't want to spend any many (like me), italki has other useful features. One of them is language exchange partner. Basically it's a way to pair you with other member who understand the languange that you are currently learning and is trying to learn language that you understand. Under this system, you and your partner take turn to teach the other the language he/she understands. Italki provides you with chat and message system to converse with your partner.

Another useful feature is notebook and question. Notebook is where you can make personal entry about your current progress and your partner/follower will be notified when it's happen so they can offer their comment/suggestion. You can also post global question that can be seen by all members. There are many language teachers that will readily answer your questions. It's a good way to build reputation and attract students.

Italki is really great is you are a social person, you can learn and make many acqauintances at the same time.
