Editor James Shannon announced yesterday that 20,000-circulation MetroBeat has ceased publication. The paper was known as Creative Loafing-Greenville until its sale by that chain to its founder, Debby Eason, in August, 2001. Of the 14 papers that applied for AAN membership in 2002, MetroBeat was the only one that was accepted. A letter from Shannon announcing that he will continue the publication as an online magazine is posted at MetroBeat.net .
