Dwell Magazine has birthed a Kitchen Blog to add to the list.
The just started on October 24th 2007 so there's not much there yet...So far colorful, contemporary and appliance oriented.
Looks like a variety of editors are posting to it. Including Sara Hart, Michael Cannell, Chelsea Holden Baker, Audrey Tempelsman, and Deborah Baldwin: who has an interesting post about trying appliances before you buy.
