Well, I guess, Italki is nothing alike to Facebook or Twitter... The only point is people can talk to each other, but on the other points this social network is absolutely different. It doesn't mean you can't find a friend here - some people from here meet each other in their 'offline' life. But I think here we are a bit depersonalized - we meet each other considering not our interests and habts, but languages we learn and speak

italki very different from facebook and twitter. Italki is a site to learn a new language and a new culture. Now this has italki premium members where members are listed as a member is a member that serious to learn a new language and a new culture. Also for the owners of the members would be free wrote the book notes, discussions, questions, these will all be exposed. For members who do not use premium member these services are limited in use italki facility.
But you can find a partner to learn free.

You might consider the website as a language center where it provide you wonderful opportunity to practice your writing . You may view some standpoints here from all over the world . Honestly to say , it is hardly to find your Mr.right here for some people who want to fall in love with aliens  .
