Hello Qing,
I like your idea of creating a more practical social media that for amateurs where to post a recent widespread event. In this PLN, people have access to more detailed information that concentrated fragments of information from various social platforms. People who are interested in know the detail of the event would join and start the discussion. This environment is more relaxing compare with the academic one.
Hello Lawrence
I like your idea of increasing brand awareness through social media. An effective PLN has a huge impact on branding. People in this PLN will be influenced by your postings and will spread to people around them. With this link effect, more people will follow the campaign in a way that is free and efficient.
