Not so yummy: Yesterday GraceAnn Walden did a Brett Favre on the Yummy Letter, only instead of Walden deciding to retire, its was the Yummy Letter that retired on her. Publisher Susan Dyer Reynolds delivered the grim news about the foodie newsletter, which launched six months ago: I am sad to say that today's Yummy letter [sic] will be our last. GraceAnn and I have savored every minute of it; however, in these tough economic times we simply could not raise enough advertising dollars to sustain the project, and, unfortunately, we have run out of money. Walden, ex-Chron Food staffer and originator of its "Inside Scoop" column, says she'll continue to yack on KGO, both on the Ronn Owens show and as sometime host of Gene Burns' Dining Around, and continue writing the "Chef's Chat" column for Northside San Fancisco. As a food reporter for Yummy, Walden was ballsy and occasionally crusty, possessed of a Rolodex bristling with chef's cell numbers: a real maven's maven. The Yummy Letter failed to reach a wide readership (hard to do in six months), and Walden never shied away from plugging her other endeavors, from neighborhood walking tours to her own newsletter. But hey, it's hard out here for a pimp. We'll miss ya, GraceAnn.
