People whose lives are FB and Instagram are following celebrities and getting caught up arguing with strangers over reality TV drama. None of this exists in the Metaverse, there are no Groups or Pages where this type of discussion could take place. That's the biggest issue with Horizon Worlds -- you are expected to go there and talk to strangers.

That is 100% unlike the FB experience, where someone else provides a prompt (post), and you join in the comments.
