The engine had barely warmed up on the crazy astronaut story, and then Anna Nicole Smith had to go and die. CNN, Fox News, MSNBC, and so forth only have so much bandwidth available for pointless, sensationalistic stories that demand our constant and unrelenting attention. It'll be interesting to see how they carve this up.
If it were up to me, I'd just go ahead and do a split-screen. Crazy astronaut on the right and Anna Nicole on the left. And on the bottom of each screen, a constant scrolling news feed devoted entirely to the story on the other screen. That's really the only sensible way to handle this.
