There is a liberal politics board(Democratic Underground) that I used to dwell at that had at least 5 "OMG THE WURLD IS GONNA END" type posts a day. Anyhow, one day not so long ago they had a really bad day where they had about 25 real stinker threads about how we shouldn't bother to get lunch because the looting and burning will hit the burger king before anyone can make it down to the elevator.
That's definitely too much (very unrealistic) doom and gloom for me. My version of doom and gloom is the old Johnny Carson joke. "World ending at 10pm. Film at 11pm."
