L.A. author, humorist and kitschy snapshot collector Charles Phoenix will share his vintage Valentine's Day slides with Martha Stewart on her syndicated TV show on Thursday. I have no idea when she's on, so check your listings.

But before that: If Martha is low-brow entertainment, here's the high-brow. Dana Gioia, chairman of the National Endowment for the Arts, will speak to a Zócalo group Wednesday at 7:30 pm at the Barnsdall Gallery Theatre. It's free, but reserve.
