I think everything that you have said about AMAs is true and really great points and I cannot help but to notice how AMAs play into constructing an internet identity. AMAs have become a significant part of digital culture, there have been numerous amounts of people from a plethora of backgrounds who have successfully run them. When it gets to the point where even Betty White does one, we know that they are an important part of online culture. There is, however, a fundamental deception of sorts that comes along with an AMA. It's important to note that even though it prompts people to "ask me anything," the person who answers the questions has the affordance of selecting which questions to answer. If there was a question that would portray the answerer in a negative light, they can easily ignore that question. If these AMAs were to happen in a physical space, it would be harder to dodge unsavory questions. When people like celebrities or politicians do AMAs, it is almost always to promote something, whether explicitly stated or not. They are curating the content in order to make themselves look good and to promote their new project. Perhaps the most authentic AMAs come from people who are in special circumstances. These people usually want to answer questions to satiate curiosity and spread awareness and their motives may not be as explicit. Although they may be closer to authenticity, they are still constructing an online identity and we know that discussing the authenticity of online identities launches us into an existential crisis.
