People used their real names, and even posted where they were from on Usenet. There was a sense of community and there was a term -- netequitte -- that described how we would act towards one another. If you used a handle, watch out, you might be a troll, and you certainly weren't going to be immediately trusted and had to build your reputation.

Replies went below the body, not above it, and everybody hated Microsoft Outlook for unilaterally deciding that replies go at the top of a message. Similarly, people hated WebTV users for just bringing the level of discourse to the gutter.

Web forums were fast and also a good place for community, kind of a gateway from Usenet to modern discussion forums. When people passed away we would all attend the funerals or whatever if we were close. There were 56k warnings in the subject line if a post had embedded images.

In the metal scene, maybe other places too, you would trade CDs. So like you had a burner and someone else had a burner and you would swap copies of CDs that you had for something they had. So you could build an entire huge collection of CDs and demo tapes cheaply. There were trading lists and people had reputations and who was reliable, who was a rip-off, and who was an idiot for burning 256kbps MP3s and selling them as CD quality (yes, you could tell a difference back then; something we still haven't recovered from now that everyone is streaming). If you didn't have anything to trade, you would pay like $8 for a CD. Black Friday 2000 was huge because burners only cost a couple hundred dollars that week, so it was a wise investment.

Sometimes the traders of new music were the band members themselves, and that was always fun to find out. I got Sons of Northern Darkness from a guy who was in the studio. I got a copy of another highly respected album from the bassist of that band who just wanted people to hear it. They would just mail it your house and you would receive a CD in an envelope with chicken scratch handwriting on it.

When Puritanical Euphoric Misanthropia was leaked in the trading community, it blew people's minds. People were like holy shit this meme band that everyone hates just got serious and took our entire genre to the next level. I cannot understate how big that album was.

People sent checks via the mail in exchange for goods. Online transactions were still done this way instead of all electronically. So you would purchase online, get an order number, put that order number on a certified check, and mail it off. And a week later you had your stuff.

Also everybody had a customized desktop. Not just the wallpaper, but the themes, the colors. There might be a talking cat that sat on the desktop and would get up and walk around and poop and tell you what time it was. Everybody had unique desktops. Everybody had different fonts. Maybe cursive, and in pink and yellow and that was what the entire interface looked like.

Slashdot was huge and the original Reddit. There was a Slashdot effect where if they linked a site, that site would suddenly get so much traffic that it might die. Also in those days you could tell if a webpage was using IIS or Apache because the Windows server was always slower to serve webpages. When Dell entered the server space people laughed because Dell was not an enterprise brand and who would ever seriously use x86 or Windows on a production server?

Online chat was a thing with a/s/l and everyone had an online significant other with whom they would chat about things daily, but who lived like 5 states away and no you would never, ever go meet them. Even suggesting such an idea would usually end the friendship. Everybody had an online diary with a guestbook and a stat counter -- showing how many page hits you had.

There was less corporate ownership and more independence back then. It was okay to be different and unique. The Internet wasn't just like 5 websites.

I think the Fediverse -- Mastodon especially, comes closest to recreating that turn of the century feel.
