Well, for some of us that'd probably have been yesterday. But, in my timezone and side of the date line, today is 404 Day. It's initially an EFF thing, and I suppose it still is 'cause few folks know anything about 404 Day.
404 Day
It's 404 Day today. To honor the day, talk shows, seminars, and other activities are being held around the country. Come out and uniquely enjoy the event.
