 With regard to this and other comments on the talk page, I don't know if you intend to convey hostility, but that's the vibe I'm getting. I think everyone in that debate is pretty reasonable, and we're all working toward a more encyclopedic article. There's no need to fight - reasonable editors can come to a version that is acceptable to everyone. I think the article is already better, with the Sagan/Nightline trivia gone and the sourcing improved. So let's work together and get it right, OK? -)
