Today at Flavorpill, we liked Architizer’s brief history of moving buildings, a roundup inspired by Richard Neutra’s Maxwell House. We watched a clip from Claire Danes’s new Showtime series Homeland. We looked back at the Civil War, 150 years later. We were kind of confused by the reasoning in Ashton Kutcher and Demi Moore’s “real men don’t buy girls” PSAs. We learned about the algorithms Facebook uses to decide what news makes it to the top of your feed. We were inspired by How About We’s five date ideas for Jane Austen superfans. We wished that all interviews — or at least all interviews with Zach Galifianakis — could be done Mad Libs-style. We really felt our age while looking over 50 magazine covers from 20 years ago. And finally, we read Mark Twain’s amazing letter to Walt Whitman in celebration of the famed poet’s 70th birthday in May of 1889. Can you imagine a better present?
