Pinky's Paperhaus is in the sidebar of the LA Times blogging article. While falling into the "arts" category would have been, um, more intellectual (Mark is there, of course), I'll take "out there." Why not.
The very smart and occasionally silly Lee Goldberg is also on the list, for his behind-the-scenes blog about being a Hollywood writer and producer. He just visited the Haus with his brother Tod; they talked about their new books and about selling dirty socks on eBay (well, Tod talked about the dirty socks).
If you had the patience to come here via the Times, Pinky's Paperhaus podcasts interviews with writers as they guest DJ and talk about their work. Plus other writerly things of interest. Like Jack Klugman.
