Shuggie Otis and Webvan: … Brad Kava of the Mercury News caught the musician’s show at the Fillmore, and was less than complementary. (Joel Selvin of the Chronicle was no kinder.) It’s been a while since I’ve seen a really rough review of a performance in a local daily — since the Tribune’s CUE section dope-slapped Mariah Carey a few months ago. Speaking of the Trib, they’re saying that San Carlos, Calif., police are on alert regarding Webvan layoffs. For a second there, I was picturing angry customers wandering like zombies along tree-lined subdivision streets, grocery lists and freshly printed-out directions to brick-and-mortar stores in hand.
