I got my start (in programming) building my first e/n site (god has it really been 18 years...). My personal understanding was that "e/n" stood for "everything/nothing". In my case, this was exactly correct.
It was a place for my friends to post stupid stuff, a place for me to experiment with css and php, build new "features" just for fun. It was an open playground in a new world. It was a lot of fun. I also just remembered how it was hosted. I became known as the neighborhood kid who collected old computers, so I ended up with a bunch of weird hardware. The site was originally hosted on a 75mhz intel something or another sitting behind a 133mhz linux frankenstein gateway in my bedroom. I remember getting mad at my internet provider when they claimed I had used up "all 10 gb of data", when I clearly had the bandwidth logs that showed it wasnt possible!
The other cool thing was connecting with other e/n site owners who were also doing their thing. Sometimes you'd collaborate or ping each other's APIs, other times participate in their own experiments. Thousands of little web sites with micro communities built on spaghetti code, almost all have certainly faded away through the various ways that tiny sites die: a web host gets sold, an upstream system upgrade botched but not addressed, a missed payment, an unpatched vulnerability. Maybe today the owner still maintains the domain name out of nostalgia. Shoutout to gyrate.org and sejje.net; Rest in peace, frikk.tk
