Our very own columnist Frank Rich will host an AMA (“ask me anything”) on Reddit tomorrow, Thursday, August 30, at 11 a.m. ET. For two hours, he’ll answer your questions about politics, the media, his recent pieces, and anything else that comes up. You can follow along at http://reddit.com/r/IAmA (you don’t need a Reddit account). Get there early, as Frank only has a limited number of Nora Ephron stories.
