It surprises me when I watch What is a Personal Learning Network (PLN). I never thought about when I post or ask questions on social media belonging to PLN. Because it is not a systematic learning program. In the video, it shows that we should see ourselves as networked individuals. Smartphones and Wi-Fi have brought people closer connected. I agree that this change has a significant in our lives. We can find all the knowledge we want to know online. However, the network how to distinguish what knowledge is available to be learned by different people. There is a way that I think we could establish a limit system. For example, we could restrict teenagers not allowed a type of search unless they have the permission of their guardians.
