> I think there are lots of other things going on there over and above the moderation issue, but one is that the early Internet culture was very self-selected for people who thought that the ability to talk to people and the ability to access information were morally virtuous.

Honestly I think it mostly self selected based on who had the technical ability to participate, especially at that time.

Also early internet access was gated by institutions. Most people were using their work or school internet access to be online, and so behavior was naturally more controlled. When I was first online (circa 1990), I could have been "kicked off the internet" by my college's IT department.
