I wonder: if some paranormal entity plunked its magic twanger and let everyone on Earth eliminate each other on the slightest whim with the same ease that members of online communities can leave in a huff or banish one another, how long it would take for the Earth to become wholly depopulated?

I'd give it three days, tops.

Time for a "Button, Button v. 2.0," methinks.
