Concern about Portuguese corrections in italki I have seen that some notes written in Portuguese by foreigners are corrected in a wrong way by Brazilians. At last in Brazil, most people lacks Portuguese knowledge, seriously! This fact is worrisome. Portuguese is a complex language, studying grammar is not far enough and is unproductive. To learn it, it is necessary to read a lot. I think that the best way to learn Portuguese is by reading a lot. Sure, grammar rules are important too, but, for me, it is a secondary requisite. I'm certain that many people have the same opinion. By reading is possible to learn implicitly how to write and talk Portuguese well. The problem is: most Brazilians don't read and have few knowledge about grammar rules, even the graduated ones. A recent research showed that, on average, Brazilians read only two books a year. Thus, unfortunately the people that are trying to learn Portuguese by italki should not rely on all corrected notes.
