Well, this is a difficult topic, I don’t have much to say about my experience with blogs but I will try to give you my opinion.
About my experience writing blogs I can say that it was a very different manner to learn vocabulary and grammar. At school the most similar experience was write a letter to someone haha
I think that it was a nice experience, where we had time to think (and write) about things that was not related to university or study (I have to exclude the post about our favorite subject), but I have to admit that I like more secret workings because was shameful for me write public posts. Another thing that was difficult for me was that sometimes I hadn't ideas to continue writing.
I think that my vocabulary is a little extensive than before and that my reading comprehension improved so much practicing with the posts of my classmates.
Something that I would include is to read out lout our posts to improve our pronunciation, thought maybe it isn’t necessary with the others activities that we did at class. Maybe the correction of our posts could be send to us evenly to know in what we are wrong to try improving it.
