I'm fascinated by the doomsday hive mind. I don't know why, but the fact that some souls think they're breaking away from the pack and grandstand, shouting about knowing how the world will end, always entertains. Michael Rupert in particular, who first caught my attention in "Collapse", became one of my favorite. Not because he was crazy, but because the things he said, in a real way, kind of made sense.
On April 14th of this year (2014), he took his own life. Nonetheless, his life was a fascinating one and The Verge has done a wonderful, lengthy write-up about this tortured soul. Find it here.
