So I've been reading "Surfing on the Internet", written by #JCHerz in about 1994. It talks about #MUD and #MOO. I had only heard of them in passing back then.

Reading the book, I realize: Whoa, these things are like multiplayer #interactiveFiction . Not just that, but the world can be programmed.

It's like the #Emacs of gaming.

Some #MUDs are still active now. Some of these games have been going for 30 or 40 years.

What are good resources to learn about MUDs?
