Hi Shanshan,

Great post. I agree that social media can help us learn new knowledge. Because everyone has different ideas, we will discuss and explore different viewpoints in the community. After this process, people will make progress.

Hi Alison,

Your blog looks very clear and I like it very much. However, I don’t understand what you said “social responsibility is the best motivation for establishing PLN”, and I hope to get your feedback. In addition, regarding the limitations of PLN, your thoughts are very comprehensive, especially on the last point, because it is online communication, so we may not know each other.
