Quora is one of the best social networks in terms of questions and answers. Needless to say, there are numerous questions and answers about the English language. This is a particularly good example:

QUESTION

What is the best place to learn English: London or Dublin?

ANSWER

Your home.
You just need an Internet connection and friends who speak English.
If you start using English every day for real-life communication, you will be fluent in it before you go to London or Dublin. Watch movies and TV series in English. Think about the time and money you need to go overseas just to “study” English. It’s not a science you need to study. It’s a language. You need to speak it. You will be fluent in it without any studies.
Go to London or Dublin for job interviews or just travel, not for English learning.
Start using English for most of your daily communication, don’t waste your time and money.
