That’s interesting to think about usernames when considering true identity. I agree with you that people are much more hesitant to comment or share content on Facebook because it will forever be attached to them. Instagram makes it even more permanent. At the least on Facebook you can change your preferences and erase enough information to hide much of what you choose to share. On Instagram you cannot edit or delete a comment. The publisher of the picture must delete the entire post. People are much more likely to be truthful when their name is not attached. I agreed with many of Hogan’s points about usernames and thought about how Instagram just erased thousands of “throwaway” accounts and had an uprising because most of their users, including myself, lost a lot of followers.
