Who are you?
This is the question that everyone has to ask themselves, especially where your online identity is concerned. Because let's be honest, we are seen differently by different people. Whether in real life or online, we all have different persona's, depending on who we interact with. It makes absolute sense that we would have different identities online. Your Facebook/Meta identity will be different from your LinkedIn identity, which will be different from your Twitter etc. identity. Not that it is that different in real life. We are different people at home, with our friends versus at work, with clients etc.
In other words the idea of multiple persona's / identities is not new.
