There are 342,302 total writeups on E2 that haven't been removed from view which weren't automatically added from the Webster 1913 dictionary. (102,719 entries were "auto-noded" from Webster's and most have been around since E2's inception.) Given that a great many of nodes from before 2000 were deleted in recent years, I'd wager about 300,000 of those writeups have been created since March 2001.
About the time we think we can make ends meet, somebody moves the ends. -- Herbert Hoover
