I'm Herostratus, I'm a Wikipedia editor and have been since 2005.
My user name was taken in ironic memorialization of the original Herostratus, the greatest vandal of all time, who destroyed the Temple of Artemis at Ephesus, one of the Seven Wonders of the Ancient World.
I created the Wikipedia Service Awards, which I conceived, wrote, made the images for, published, and shepherded thru deletion attempts. (Other talented editors and better artists have since expanded and improved the awards, of course.)
If I should ever abruptly stop editing, the explanation is probably related to this.
