The purest representation of this I can conceive of is SDF. See: SDF.org I remember reading the descriptions of user areas on their MUD when I was a teenager in the 00s and feeling like it was a portal back in time (to the early 90s, admittedly) when the internet was more about creation and communication rather than media consumption. It was incredible to feel the continuity in this beautiful, fragile and very very idealistic but which was able to be true to those ideals as well. The area I refer to is still there in the MUD, by the way, it is called Swanbrook. If you ever play, look behind the altar and you get to read a message from the area's creator, signed off as Snowbird. That message actually introduced me to the rolling stones. Not bad for something written thirty years ago on a very obscure bit of the internet.
