If Facebook went away tomorrow, what would you miss about it?

Personally, nothing. (Perhaps if others have the same answer, they can reply to this to keep the top level interesting.) But I'm curious...

At this point, the only thing I use it for is to get tour dates of a few bands.

Nothing. Quit using it 7 years ago. No instagram account either.

I'd miss the gravitational effect it has had on normies and boomers. I don't want those people joining Mastodon and stinking up the place.
