The best way to learn a language is to practice that language. So if you like to learn a language in easy and faster way, you should some online language learner forums. Thesen are all-in-one language platform connecting people from all around the world. Here you can talk to the native speaker for language learning.

Thank you for the full list provided, I just think that talking with other language learners or better, native speakers is the best and fastest way to practice a language, we just love the way ijtalk (http://www.ijTalk.com) is maintaned and developed, it is easy to find someone to talk with without a need to use external tools. Of course learning the basics should be done by other learning tools (like grammar book or online course).

They are so many new languages learning softwares created each month that writing a list is a real challenge. You can find reviews of some (in French, but a translator is your friend) with pros and cons on this non commercial blog http://labdeslangues.blog

Thank you Lara for adding languing.com. It definitely sounds very interesting. I'll give it a look. :)

Šiuo metu pati mokausi anglų kalbos, tad šio straipsnio dėka sužinojau, kur papildomai galėčiau patobulinti šios kalbos žinias. Mano nuomone, kalbų mokymasis virtualioje erdvėje yra itin puikus būdas norintiems išmokti kalbą ar pagilinti žinias, atliekant įvairius pratimus, kalbėjimo, rašymo užduotis.

Norėčiau pasidalinti naudinga nuoroda http://rolanda.lt/video-patarimai/, kur mokytoja Rolanda pataria: kaip kalbų mokytis naudojantis SuperMemo puslapiu; kaip daugiau sužinoti iš puslapio SnappyWords; kaip mokytis žodžių naudojantis Quizlet puslapiu; kaip naudotis edX kursais; kaip ieškoti filmų Youtube ir kaip sužinoti daugiau iš IMDB. Tikuosi, kad ši nuoroda  Jums bus naudinga.

For me the best one of the list is duolingo, it's free and really powerful. But as a social network I miss languing.com is a free language social network. I have been learning Russian for over a year for free with native speakers. It is so handy because it has a video system integrated in the browser, a translator and you have so many opinions and rating of all the users.

What I do when I contact a new user, is to check his/her ratings then I prefer an audio call and when I trust him/her I change to video. Moreover it has an instant video match feature, so you just press a button and start to practice with a user that matches your languages.
