Guest-blogging at Penguin

THE BANANA BLOG is about the world's most endangered - and dangerous - fruit. THE BIG PARADE is about stairways, route and transit geekery, and pedestrian pursuits in Los Angeles. You can also read all the topics at once, which might also include productivity, geekery, DIY whatever, mountain biking, stuff that I think is funny that nobody else likely will, and other boring, useless crap.

Nobel Prize winner Paul Krugman recommends it. Listen to my interview on NPR's Fresh Air. My own op-ed in the New York Times.
