Google has a 20 year history of posts on Usenet. The archive dates all the way back to 1981, and covers such interesting topics as Linus Torvald’s announcement of Linux, the first post from an AOL account (N00B!), first post about the show Friends and many other interesting posts. They’ve even singled out the first “get rich quick” scheme.
So be mindful of what you post on Usenet, you might see it again in 20 years!
Some great stuff there…
