Red Herring promises a really fake coverMobile Rules, a business-plan competition for wireless startups, is promising winners the ultimate booby prize: their photo on the cover of Red Herring magazine next March. One small problem: With printing and distribution bills reportedly unpaid, the Herring has given up on the paper-magazine business. An online-only magazine cover somehow seems unsatisfying. But give Herring publisher Alex Vieux this much credit: It's a very economical prize.
