What’s more important is the rules of the fictional universe are internally consistent to prevent that loss of suspension of disbelief.

Good point. I like to completely escape, be presented with interesting points of view, or be entertained, so I tend to enjoy sci-fi/fantasy, comedy or drama.

And so, like in the movies, in a place where you can be anyone, I am whoever you want me to be.

In this context, it doesn’t really matter to me if you are the person in the Barbie movie and or an awkward 14 year old that idolizes her/you, but it raises a good point. Before any kind of mass media, Cicero wrote about the power of eloquence and the importance of the wisdom to use it responsibly. That is more true today that 2000 years ago. Social Media gives the most persuasive people an earth sized megaphone. ANYBODY, with sufficient skill can post something that goes viral and have it reach millions over night and influence them including billionaires and politicians.

The aforementioned power gives platforms (and moderators) a lot of power because they control what people see. I’m really hoping for the Fediverse to succeed because I hope to distribute that power across borders and instances. There is still the age old problem of who should be in charge of the various communities. We have seen what can go wrong with Reddit where the community creator has it.
