Ever since I took a class called "Cyberculture" while attending Griffith University* in Australia, I've been fascinated by internet lore and the stories of how the web was built. One of these stories that I recently came across was about "Eternal September." It comes from the thinking that when the internet was mostly restricted to university students, websites were flooded every September with new users that hadn't yet learned netiquette. Over the course of this first month, their upperclassmen taught them how to behave online. The result was what were probably pretty well-run little communities.
In 1993 the web became more accessible to the masses with AOL and Compuserve, with new users not yet savvy in the rules of online behaviour arriving year-round. Thus, September 1993 was dubbed the "Eternal September."
If you're super into this type of thing, it looks like there is a little program that you can download here that will calculate the current day of September, 1993 that we're at (looks like it's day 4242 of Eternal September).
