It seems The Telegraph has found me out. After all this time of artworld anonymity, it has been revealed. The Artswipe is "cyber granny", not supernanny as some have conjectured. The Telegraph "outing" is timely, seeing it came just after Simpleposie from Toronto pondered in her "question for the day" a querie that most Sydney-siders stopped asking long ago, "What is Artswipe?" (scroll down to question #2156 - I thought I had lots of questions!)
Apparently it doesn't stop there. YouTube has found me out as well. Smile, smile, smile.
