anki & Lang-8

In my opinion neither are as good as other language sites such as Quizlet and Duolingo because of the fact that to use Lang-8 you have to know the language and you can do the same journal writing with Weebly and when it comes to Anki and flash cards Quizlet it better because you dont have to download Quizlet and you get the same features most people had troubles downloading Anki anyways and that is my personal opinion
