The word “community,” a timeline:

1950: The people who live near you and help when your house floods
1990: A group of people with shared interests who meet regularly
2010: An email list you can’t unsubscribe from
2015: Anyone who follows a brand on Instagram
2020: A Discord server with 40,000 strangers and one moderator
2024: A Slack workspace your company forces you to call a community because it’s cheaper than actual culture

The 1990 one applies going back, too. Service clubs were very popular postwar into the 1980s. Your local chapter was your community. I think they faded because entertainment options became more alluring. I was in one as a teenager. Our state convention drew 10k people one year.
