Those of you old enough to remember Webvan will likely greet news of any grocery delivery service with a healthy dose of skepticism, and rightfully so, but I think that the folks behind Relay Foods, currently in operation in Richmond and Charlottesville, are onto something.  Here's Bookofjoe's review of the service and here's the "How it works" page on their site.  Very cool and something I'd love to see in the Triad.
