Big Social Language Learning Community
One of the largest and fastest-growing online social language learning networks, iTalki offers a sophisticated user interface, a large and growing user base, a shared file database of lessons and helpful info as well as a great list of language-learning resources (you have to join to access them fully).
This is a great place to meet people for a language exchange over VoIP (Skype, Gizmo, etc.) and with instant messaging. You can meet and maintain language study exchanges with people from all over the world!
An excellent advantage of italki.com over some other social language learning networks is that their site has been localized in Arabic, Traditional and Simplified Chinese, French, German, Italian, Japanese, Korean, Portuguese, Russian and Spanish, making it easier to use the site if your native language is not English.
This site is an excellent way to meet, learn, teach and exchange cultural information with new folks from around the world.
