Comments of YouTube

In my opinion, I consider YouTube is a great digital information sources. If I want to search some information about teaching such as Communicative Language Teaching ( CLT) the YouTube will appear variety teaching data. Then most of those videos are creating by learners thus everyone can be director or protagonist. By the way learners do not need to pay any extra money; those materials are free to download. From these reasons, I think YouTube is a good platform to let learners share and perform.
