An illustration as to how little mainstream penetration the #fediverse has actually made: Currently the #NFL playoffs are happening in the US. There's a single game happening right now. The #reddit game thread got ~34k comments in the first half before the moderators locked it and created a dedicated thread for the second half to work around reddit scaling issues. The #lemmy nfl community thread is idle.
At least in the US, the fediverse really doesn't register in any meaningful way yet.
