Hi Yuanweihou,

I am surprised by your example about virtual avatars. You are definitely right that virtual avatars are not technological products for us to live in a virtual society. Instead, it is an approach for us to present ourselves from different aspects, such as appearance, preferred styles and personal interests. In addition, you mentioned in the second question that health practitioners can build professional identities. When they present generated healthy information, nearby communities would get scientific and useful medical professions. It is also a good example of professional approach to digital identity. All in all, your examples are insightful and concise.
