You know, I like Neil deGrasse Tyson - he does a huge amount for public outreach about science, and has even appeared on the Colbert Report (which I would love to do, since I think Colbert's observations about truthiness and wikiality have a lot to do with science today). However, this article is exactly the sort of hype-ridden malarky that really hurts science in the long run. Our risk of being swallowed by a black hole is negligibly small, and the science in the article is appallingly dumbed down (black holes were long thought to be roughly stationary? With respect to what, exactly?). While it may get people's attention, implying that it's likely that roving black holes in our neighborhood are going to kill us all is not the best way to get science in the public eye.
