Everything2 (E2) is an online collaboration of all sorts of writings/articles submitted from people all over the world.

"Everything2 is a collection of user-submitted writings about, well, pretty much everything. Use the search box or follow the links to explore.. In a nutshell, Everything2 is...
A Place to Read - E2 offers you a huge amount of original writing of many kinds. You'll find informative articles on just about anything you can imagine, but you'll also find humor, poetry, fiction, opinion, criticism, personal experiences and other things that are hard to categorize. Articles are linked together deliberately by authors, and by readers passively browsing. Just by following links, you are contributing to the integration of the database" [1]


"E2 users called noders create entries called nodes and add information in multiple writeups. Only logged-in users can create writeups, and only the author of a writeup or an editor appointed by the site administrators can edit a writeup. E2 categorizes writeups into thirteen types: person, place, idea, thing, dream, personal, fiction, poetry, review, log, recipe, essay, and event. Two additional writeup types, lede and definition, are usable only by editors and are applied retroactively. Writeups are written in a simplified HTML dialect and do not contain images. HTML, short for Hypertext Markup Language, is the predominant markup language for the creation of web pages. ... chatterbox feature, only an irc channel. Messaging is done by editing other user's home pages". [2]


"E2 is not Wikipedia. It does not pretend to be, and I think that (except perhaps for a very small minority) its users do not want it to be. On Wikipedia, if you can find something and it's in some way important to something, you can write about it. Your writing will stick around until someone decides that it's flawed in some way, but even then, much of your original work will live on in places. E2 is not like that. E2 is like the real world.."[3]


"E2 is like walking into a conversation that's been going on longer than just about any of the participants can remember." [3]



"Everything2 is not about having everything; it's about working the same way as everything. It's something that is really hard to find out there, even on the Internet. I'm glad that E2 works like this, and I hope it stays this way". [3]
