BEST LOCAL WEBSITE www.artblog.net It would seem that Miami plays host to two gentlemen by the name of Franklin Einspruch. There's the Einspruch best known to readers of the New Times as a thoughtful, considered, and genteel art critic. Then there's the Einspruch who produces artblog, a freewheeling site where he shoots from the hip about the Miami art scene, waxing poetic on the good, the bad, and the aesthetically ugly. Best of all, once Einspruch has offered his delightfully bitchy piece, much of the local art community -- artists, gallery owners, fellow critics, and the entire intellectual peanut gallery -- weighs in to post comments, responses, and angry back-and-forths concerning everything from new shows to hyperbolic reviews. Call it an ongoing testament to that part of Miami's creative energy which rarely makes it into newsprint.
