Hi Ruobing
I think what you said is very reasonable. Students are particularly fond of using social platforms such as email. As far as I know, in addition to what you mentioned, Academia, Weibo, etc., they can also meet different people from different platforms, who are likely to help you in your career. Of course, in today’s big data network, we must protect our privacy. If my personal information or photos are maliciously used, it will have a great negative impact. So， all kinds of platforms recall user privacy as a standard to protect everyone’s information, only in this way people will be willing to share on them. Your V+R map is also a good indicator of your abilities in various areas, and we can also find your best points based on your software.
