What’s the most "old Internet" thing you miss?

Dial up BBSs. They didn't even technically use the internet as we know it now. Some nerdy person would have a dedicated computer with software such as message boards, text-based games, etc. They would advertise the phone number to dial to access the board, or multiple phone numbers if they were rich. These were hobbyists who wanted to provide an environment for like-minded people to chat, and they were always local people.

I would sit there in the evenings and dial up one after another, and go into the chat boards and play games like L.O.R.D. (Legend of the Red Dragon), and that's how I spent my evenings. Around 10:00 or 11:00, I would log off the last one and get on the internet proper, so I wasn't waking anybody up with dial-up noises. That way they didn't know how late I was up.
