It seems that Heshy is gone!
Personally, I can't say that I'm sorry to see him go. He was sort of a blogger arsonist - just throw something out there on the fire and see if it'll burn. I do, however, have one regret about his disappearing- he never ended up explaining on his blog why he was opposed to the concept of alien life. I would have liked (in a morbid sort of way) to have heard that.
