What are some old web features? Or quirks?

I saw someone mentioned a guest book and I had to look it up. Apparently people would leave public messages on a dedicated page and you can reply to them. Guess spam ruined that. Any thing else, didn't really get to experience it being young and all. Maybe some could make a comeback and one of us could implement it. submitted by /u/Successful-Title5403 [link] [留言]
