What Ever Happened to 'Toothing'?

Jim Hanas excertps from his very funny article on the quiet disappearance of last-year's promised digital bacchanal. "Remember 'toothing'? It was a craze that was sweeping England last year as bored commuters arranged sexual encounters using Bluetooth-enabled cellphones. You probably read about it over at Wired or Reuters or the BBC. There's a decent chance you even blogged about it. Well. What happened?" Update: 04/05 00:10 GMT by T : Hanas writes with a followup: "The original source on the whole toothing thing has just admitted it was a hoax -- in response to my email and your picking up of my post."
