There is truth in the above.

In 1990 the usenet group
rec.boat.paddle
had people on it then that reminds me of Moparts members from 5 years ago.

No advertising on usenet in 1990.
Differing opinions for sure, but mostly respectful conversations.

Reddit is somewhat like usenet, but with far more “noise”

The spontaneously formed Reddit group DRASTIC of “never met in person” virus investigators
reminds me of the spontaneously formed usenet team who, despite never having met before, went to and won the Nation Swiftwater Rescue competition.
