Which activities did you not find useful to learn English? Why not?

Postcads. Why? Because we spend a lot of time to recorder the thing, after we have to put it in the blog, and also put the videos on blog because sometimes it's very slow and it takes a lot of our time and I think that blog is not a form for learn English, only the texts that we make at class and after teacher correct it, because the texts that we put for our taste we don't know if it is correct or a lot of mistakes. Porfolio also takes a lot of time, because there are texts that we do at class an there are also correct and I don¡t see necessary to spend time putting it on blog, because we have to do also de blog! Well, I think that people that haven't got computer has to be a little bit angry because it's a shame that we have to spend time searching programs to put videos and postcads and this things.
