Greg Dworkin's round-up: WaPo sale, Twitter expands the conversation, "The Tea Party's Path to Irrelevance," National Geographic on "daylighting" of urban rivers. That reminds me to take a look at Tim Murphy's MoJo piece, "Meet the Town That's Being Swallowed by a Sinkhole." Next, Joan McCarter joins us for a look at what's happening and what's to come on the Daily Kos front page, and we talked about Idaho's wildfire season (and the plight of the "Smokejumpers"), upcoming coverage of the Romney speech, the possibility of a government shutdown showdown, Obama's Leno appearance, Liz Cheney's carpetbagging, the latest terrorist threats and how they were uncovered. Also: the latest on crazy cop Mark Kessler. Finally, the start of what'll be a continuing discussion of what Jay Rosen called "The Toobin principle," the web of precepts, principles and contradictions inherent in the national security versus free society debate.
