Greetings, TPM readers, I'll be your guest-blogger from the day. You may remember me from a stint last spring, or know my exciting TPMCafe blog, or my other blog, or possibly read Tapped where I'm a contributor. At any rate, I'll try and shift to a more in-the-moment subject as the day goes on, but last time I was a guest here it was all Social Security all the time, so for nostalgia's sake if nothing else take a gander at the Century Foundation's latest on Chile's not-so-pleasant encounter with pension privatization.

If you're so inclined, drop me a line at myglesias at Comcast dot net.
