While I wouldn't want to eat one, they clearly make you think about many issues -- some scientific, and these days even moral. But some think more clearly and explain things more generously than others.
The only involvement I can claim with this excellent post by Sabine on Backreaction is finally pushing her over the edge (with this) to blog in public about her take on the non-dangers of black holes, micro or not. It's a great read -- with something to say to many people, including the folks in the media who have really been milking the doomsday story dry.
But who the heck made this crazy video of the earth being swallowed by a fictional black hole Beyond a certain point this goes beyond speculation, and becomes manipulative demagoguery.
