@mentallyalex That's not so different, but one big departure is that, offline, we don't often choose our nicknames. They're given to us by friends or family. Did you choose "Alex" or did your parents just want to reserve your full name for when you're in trouble? 🤔😃
Even when we do try to choose our nicknames, whether they stick is entirely dependent on whether our friends buy in to the new moniker.

That's very different from online, where we can assign ourselves different handles based on the community we're engaging with.
