Recently I discovered these...

Everyone knows there is a dearth of relevant arts coverage in the Bay Area (especially in print..I still can't believe that Kenneth Baker is the apex of art reviewing in SF.)
Well here are a few art sites that fill some holes:

www.sketchypad.com

www.libbysniche.com

plus a great new art calendar that is pretty comprehensive...it looks like they may be adding more content at some point as well.
