You know, I've sometimes wondered, too, if Joe was an artifact in the machine, some stray bit of code that self-propigated, but I've also noticed that I post at some of the same times, and they show up on the threads with times like 3:31 AM on them.
But out here on the left coast, it's really only 12:31 AM at that point. So maybe he does sleep.
Blessings,
