I think the we should use fediverse with the expectations we had using the internet of old: Don't post anything you want to keep secret, and anything you put online is potentially permanent.
I was always a little skeevy towards Facebook and other major social media sites when everyone was encouraged to use real names, post personal details, and share real photos of themselves and friends. Hell I still don't get how people here share everything from faces to nudes and not expect their privacy to be compromised.
