The first invitation to wiki was sent out on March 26, 1995 marking the dawn of a new kind of media. This birthday has been acknowledged annually since wiki was ten.
Aside: the pub manager wanted to know how many were coming. I don't know, I admitted, I invited the whole internet. He gave me his card and suggested next time I call ahead.
